Best Nickel Carbonate Manufacturers in China - yunli chemical
When sourcing Nickel Carbonate from China, procurement managers face a critical decision that impacts product quality, regulatory compliance, and long-term operational stability. Yunli Chemical has emerged as a leading manufacturer of basic nickel carbonate, offering industrial-grade and high-purity variants that meet stringent international standards. With over twenty years of production expertise, ISO certifications, and annual sales exceeding RMB 1 billion, Yunli Chemical addresses the core concerns of B2B buyers: consistent purity, transparent documentation, competitive pricing, and reliable supply chains for electroplating, catalyst manufacturing, battery materials, and ceramic applications.
Understanding Nickel Carbonate – Properties and Applications
The chemical name for Basic Nickel Carbonate is CAS# 39430-27-8, and its molecular weight is 376.17. This grass-green powdery crystalline substance has unique solubility properties. It dissolves easily in ammonia, weak acids, and ammonium carbonate, but not in water. Because of these qualities, it is essential for uses that need to control the release of nickel ions.
It's important to know how the substance reacts to heat: at temperatures above 300°C, it breaks down into nickel oxide and carbon dioxide, which is used to make catalysts. It turns into finely dispersed catalytically active metallic nickel at moderate temperatures and hydrogen. This is important for hydrogenation processes in refining petrochemicals and making edible oil.
Key Industrial Applications
A lot of Basic Nickel Carbonate is used in electroplating to keep the pH level stable in sulfamate nickel baths. Unlike nickel sulfate or chloride, it removes too much acidity without adding anions that lower the quality of the deposit or make coated layers more stressed inside. Printed circuit board makers and electroforming experts depend on this trait to keep the chemicals in the bath within very tight limits.
Another important area of application is catalyst production. The substance is used to make Raney nickel and supported nickel catalysts, which are then used in the production of methanol, the thickening of fats, and the removal of sulfur from water. Its high purity and controlled particle size distribution make sure that the particles are spread out evenly on carrier materials, which has a direct effect on how well the catalyst works and how long it lasts.
Basic Nickel Carbonate is used in the ceramics industry to add color and as a building block for electronic ceramics like thermistors and varistors. Controlled decomposition during sintering makes nickel oxide nanostructures with consistent electrical properties that meet the strict requirements of companies that make electronic parts.
How to Choose the Best Nickel Carbonate Manufacturer in China
To choose a provider, you need to carefully look at them from a lot of different angles. For battery-grade uses, nickel content must be at least 98%, iron must be less than 30ppm, sodium must be less than 50ppm, and sulfur must be less than 10ppm. Copper is an example of a trace impurity that can darken electroplating or damage catalytic systems, even at amounts below 10ppm.
Production Capabilities and Certifications
Scale of production is directly related to the stability of the supply chain. Cross-contamination risks are kept to a minimum by established producers with dedicated production lines that keep consistency from batch to batch. Yunli Chemical's RMB 300 million in fixed assets allow the company to keep running and protect it from changes in the market. This lowers the risk of supply disruptions for customers who need large amounts of chemicals.
Certification credentials are objective proof of good quality management and following the rules. Systematic quality control is proven by ISO 9001 certification, and vows to environmental and worker safety are shown by ISO 14001 and OHSAS certifications. REACH compliance is a must for companies that want to sell their goods in Europe. This makes sure that their products meet safety standards for chemicals without having to wait a long time for approval.
Technical Support and Customization
Advanced manufacturers let you change parameters like pH levels between 6.5 and 8.5, bulk density levels between 0.8 and 1.6 g/cm³, or particle size ranges from 1 to 10µm. This kind of adaptability lets customers get the best performance from materials, including Nickel Carbonate, for their specific processes without having to change the whole production process. The business technology center at the state level of Yunli Chemical offers custom solutions backed by ICP-MS and atomic absorption spectrometry to ensure quality.
For distributors and smaller businesses, minimum order quantities and packaging options are very important. When suppliers set high MOQs, it can be hard to keep up with payments and the cost of keeping supplies. Yunli Chemical gets rid of this problem by not having a minimum order size and giving away free samples of up to 500 grams. This lets technical teams do full testing before committing to big purchases.
Yunli Chemical – Your Premier Nickel Carbonate Supplier in China
Yunli Chemical was founded in May 2005 in Xia County, Shanxi Province. Since then, it has grown into a full-service chemical maker that can do both large-scale production and study. The company was named a Shanxi Provincial Enterprise Technology Center in 2019. This shows that it has continued to invest in innovation and quality improvement, setting it apart from competitors that focus on selling goods.
High-quality inspection labs with ICP-MS, atomic absorption spectrometers, and laser diffraction analyzers for finding particle sizes are part of the production infrastructure. With this analysis power, standard-grade materials can be made along with 4N-grade (99.99% pure) goods that are used as intermediates in electronics and pharmaceuticals where controlling impurities is very important.
Quality Assurance Framework
Every batch that is made goes through strict testing procedures. EDTA complexometric titration checks the nickel stoichiometry and makes sure that the Ni:CO3 ratio is right for the job. Trace impurity analysis looks for elements that get in the way of later processing. For example, iron stains ceramics, and zinc lowers the brightness of plating. Flame photometry for tracking sodium washing effectiveness stops haze from forming in electroplating and sintering defects in ceramic uses.
The acid insolubility test is a very important way to measure the quality of electroplaters. The material is mixed with hot sulfamic acid, and the leftovers are measured. High levels of insolubles cause filters to get clogged up and leave behind rough deposits that don't meet the standards for eye inspection. Yunli Chemical keeps acid insolubles below the limits set by specifications by improving the precipitation process and choosing the right raw materials.
Environmental Compliance and Custom Manufacturing
Environmental and legal forces are having a bigger impact on how suppliers are chosen. The advanced wastewater and exhaust treatment systems that Yunli Chemical has built up over many years of working with nitrate effluents allow for the production of catalyst OEMs, including those using Nickel Carbonate, that are in line with regulations. Customers who have to follow strict environmental rules but don't have the money to build their own treatment infrastructure will benefit from this feature.
Because the company exports directly, there are no markups added by middlemen, and buyers can easily talk to expert staff. Self-operated logistics makes sure that dangerous materials are handled properly and that all the necessary paperwork is filled out correctly. This cuts down on customs clearance delays and regulatory violations that stop the supply chain.
Comparison of Nickel Carbonate with Alternative Nickel Compounds
Which nickel compound to use depends on the needs of the application and how well it works with the process. Nickel sulfate is easily dissolved, which makes it a good ingredient for electroplating baths. However, it adds sulfate ions to solutions, which change their chemistry. Nickel chloride is a good conductor for plating, but it also makes tools and workpieces more likely to rust.
Nickel oxide is thermally stable for high-temperature processes, but it dissolves 5–10 times more slowly in weak organic acids than Basic Nickel Carbonate. Because of this difference in how fast it dissolves, Basic Nickel Carbonate is better for making nickel acetate, nickel octoate, and other similar organic salts that are used as surface coatings and polymerization catalysts.
Nickel hydroxide is good for batteries because it has electrochemical properties, but it doesn't have the carbonate properties needed to balance the pH of plating solutions. As a pH regulator in electrochemistry, a precursor in catalyst synthesis, and a coloring agent in pottery, Basic Nickel Carbonate can be used in a variety of applications while simplifying buying through a smaller number of SKUs.
Cost factors change depending on the business and the area. Nickel sulfate usually sells for less per unit, but the total cost of ownership needs to take into account costs for bath upkeep, waste treatment, and changes to the quality of the product. Even though Basic Nickel Carbonate has a higher unit cost, it is often cheaper when looking at the whole process lifecycle. This is especially true in precision applications where the cost of repair is higher than the cost of saving material.
Best Practices for Procuring Nickel Carbonate from China
Checking the business registration, production licenses, and export qualifications of potential providers is the first step in finding reliable ones. Third-party audits or virtual factory tours let you see how things are made, stored, and how quality control is carried out, especially for critical materials like Nickel Carbonate. Asking for Certificate of Analysis (CoA) documents from recent production batches shows that impurity profiles and technical parameters are always the same.
To get good payment terms, you need to find a balance between reducing risk and building relationships. Agreements based on letters of credit protect against non-delivery and show suppliers that you can pay. Long-term partnerships often lead to better prices, faster service when supplies run out, and chances to work together on new products that are good for both parties.
Shipping nickel compounds involves following the rules for dangerous goods in the IMDG Code for sea freight and the IATA rules for air freight. Delays at ports of entry that cost a lot of money can be avoided with the right classification, marking, and paperwork. Because Yunli Chemical has shipped goods internationally before, they know how to give the right UN number, name the right packaging group, and make a safety data sheet that meets the requirements of all customs authorities.
As much as possible, sample testing protocols should be the same as production conditions. By testing materials on a small scale before starting sample production, compatibility problems can be found early on, which saves money by avoiding costly production breaks. As a normal service, well-known makers offer technical advice during this phase, which speeds up the validation process and makes the formulation parameters work better.

FAQ
Why does sodium content matter in basic nickel carbonate for catalyst applications?
Sodium is used as a fluxing agent during calcination, which makes nickel particles stick together. This hardening greatly lowers the active surface area, which is the main factor that determines how well a catalyst works. Keeping sodium levels below 50ppm keeps the high spread that is needed for processes like hydrogenation and reforming.
How does basic nickel carbonate solubility compare to nickel oxide?
Due to its carbonate and hydroxide structure, Basic Nickel Carbonate dissolves in weak organic acids between 5 and 10 times faster than nickel oxide. This faster dissolution rate is helpful when making nickel organic salts or when process chemistry needs to release nickel ions quickly.
What storage conditions preserve basic nickel carbonate quality?
Because the material absorbs water, it needs to be kept in cool, dry places inside sealed multi-layer bags. Stability is kept for 24 months with proper storage. Exposure to high humidity leads to clumping and changes in the amount of wetness in the material, which makes it harder to figure out the batch weight and move the material around during processing.
