Graphite Powder from Manufacturers: A Widely Used Industrial Material
Graphite powder from manufacturers is a widely used industrial material. It is produced by grinding and sieving high-purity graphite. The types of graphite powder are mainly classified by particle size, ranging from 50 mesh to 30,000 mesh. The higher the mesh number, the finer the particle size and the higher the price. Previously, due to technical limitations, high-grade graphite powder had to be imported. However, with the introduction of advanced grinding machines from overseas, Chinese manufacturing enterprises can now produce ultra-fine graphite powder, which is used in many industries both domestically and internationally.

Characteristics of Graphite Powder:
- Appearance: Black hexagonal crystalline structure with a metallic sheen, feels slippery.
- Properties: High permeability, non-adhesive, and with a density and hardness suitable for various applications.
- Oxidation: Begins to oxidize at 450°C.
- Inertness: Non-reactive at room temperature, can only be oxidized by concentrated sulfuric acid or potassium chlorate.
- Thermal Properties: Absorbs carbon dioxide at 420°C, losing luster and conductivity.
- Chemical Resistance: High resistance to acids, alkalis, and solvents, maintaining excellent heat resistance and conductivity.
- Lubrication: Excellent lubricating properties, although this can be lost in a vacuum environment.
Graphite powder is thus an indispensable material in various industrial sectors due to its unique properties and versatility.
