Overview of Nickel powder  ：

Nickel powder is silver-white and has a metallic luster. Depending on the specific preparation process, its shape can be spherical, cube, diamond, etc.. The particle size of the nickel powder can be adjusted according to the application requirements. Generally, the finer the particle size, the larger the specific surface area, and the better the physical and chemical properties of nickel powder. The density of nickel powder is about 7.8g/cm3. Porosity refers to the percentage of porosity in the total volume of nickel powder, affecting the hygroscopicity, electrical conductivity, and plasticity. Nickel powder has high stability to air, water, alkali, and other substances at room temperature. It is not easily oxidized or chemically reactive with these substances. Nickel has good corrosion resistance and is not easily affected by the atmosphere and certain chemicals. It is resistant to sulfuric acid., nitric acid, hydrochloric acid, and other acids. Nickel powder is magnetic and can be attracted by magnets. This characteristic makes the nickel powder have special uses in special applications, such as magnetic recording, electromagnetic shielding, etc. In catalyst preparation, nickel powder is often used as a catalyst carrier or active component, showing good catalytic activity.

Features of Nickel powder  ：

Low cost, high conductivity, small electromobility, excellent corrosion resistance and heat resistance to solder, while sintering temperature is also high.

FAQ：

Q1:

Physical properties of nickel powder? 

Nickel powder is a gray, irregular powder with high electrical conductivity and low electromobility. Nickel powder is easy to oxidize in humid air, and the surface will form a black oxide film, preventing further oxidation and playing a role in corrosion protection. In addition, nickel powder has a high melting point and hardness, can be highly polished, and is abundant in the Earth's crust.

Q2：

Chemical properties of nickel powder? 

Nickel powder is an active metal with good chemical stability. It can chemically react with many elements to form various compounds. Nickel powder can be used as a hydrogenation catalyst in chemical reactions to promote the progress of some organic chemical reactions. In addition, nickel powder can also form compounds with oxygen, sulfur, arsenic, and other elements, which have a wide range of applications in industry.

Q4：

What is the difference between spherical nickel powder and water-atomized nickel powder? 

Morphology: spherical nickel powder has a regular spherical or nearly spherical structure, smooth surface, and uniform particle size. The morphology of water-atomized nickel powder is irregular; the particle size and shape are different, and the spherical nickel powder does not have a uniform morphology.

Purity: Spherical nickel powder has high purity and low impurity content, suitable for high purity requirements of the occasion. The purity of water-atomized nickel powder is relatively low and may contain more impurities.

Application field: Because the spherical nickel powder has regular morphology and high purity, it is more suitable for high-purity and high-precision applications, such as metal 3D printing, laser cladding, and battery cathode materials. Due to its irregular shape and low purity, the water-atomized nickel powder is usually suitable for general industrial fields, such as coatings and plastics.

Q5：

What is the difference between spherical nickel powder and water-atomized nickel powder? 

Specific surface area: Water-atomized nickel powder has a large specific surface area, making it more surface active and easier to react with other substances. The specific surface area of spherical nickel powder is relatively small, and its surface activity is relatively low.

Porosity: Water-atomized nickel powder has a high porosity, which helps to improve its adsorption and catalytic properties. The spherical nickel powder has lower porosity and does not have the same adsorption and catalytic advantages.

Electrical properties: Spherical nickel powder has high electrical conductivity and low electrical mobility, making it widely used in electronics. The electrical properties of water-atomized nickel powder may vary depending on the preparation process and particle morphology, but it usually has good electrical conductivity.
