Production process characteristics
High purity raw material processing, smelting and refining processes
High purity raw material processing, smelting and refining processes
Select electrolytic nickel or nickel blocks with a purity of over 99.99%, and remove impurities such as iron and copper through magnetic separation and chemical dissolution (acid leaching) to ensure that the purity of the raw materials meets the standard.
The pre-treatment process requires strict temperature and humidity control to prevent oxidation or contamination.
Smelting: Nickel material is melted using an induction furnace or electric arc furnace (1450 ℃± 50 ℃), and oxygen and sulfur impurities are removed by hydrogen reduction method.
Electrolytic refining: crude nickel is used as the anode, pure nickel is used as the cathode, and purified by electrolysis to above 99.999%, with precise control of impurity precipitation by current density.
Molding and post-processing
Square shaped particles
high-pressure pressed nickel powder → 1400 ℃ sintering → mechanical polishing, with a density of 8.9 g/cm ³.
Spherical particles
electrolytic nickel liquid spray granulation → rapid cooling in inert atmosphere → screening (particle size 50-200 μ m).
Heat treatment
Annealing (600-800 ℃) optimizes grain structure and enhances ductility.
Application Fields
High end battery materials
Positive electrode of ternary lithium battery: nickel content ≥ 80% improves energy density;
Nickel hydrogen battery electrode: spherical particles increase the reaction surface area.
Special alloys and coatings
Aviation alloys: added to nickel based high-temperature alloys (such as Inconel) to manufacture turbine blades;
Electroplating coating: Nickel plated rust proof for automotive parts, with a 30% increase in hardness.
Chemical and Electronic Industries

Sputtering target material: 99.999% high-purity nickel block is used for semiconductor thin film deposition.
Additive Manufacturing
3D printing metal powder: spherical nickel powder has good flowability and is suitable for laser melting forming.
Nickel particles exhibit irreplaceable value in industrial production and technological applications due to their unique physical and chemical properties.
From battery electrodes to high-temperature alloys, from chemical catalysis to electronic coatings, nickel particles meet the demanding requirements for material properties through different forms and processes.
Whether it is a dense block structure or a uniform spherical powder, the stability and functionality of nickel particles have been verified through practical experience. These characteristics make it one of the indispensable basic materials in modern industrial systems, providing solid material support for technological progress.
