Graphite Powder Division Method

Graphite powder is widely used, according to its different uses, we can divide graphite powder into the following categories:

1. Scale graphite powder

The flake graphite powder is the most widely used and is also the original material processed into other graphite powder. The flake graphite powder has good toughness, good thermal conductivity and corrosion resistance, and can be used as refractory materials, wear-resistant lubricating materials, conductive materials, casting, sand turning , Die and high temperature metallurgical materials.

2. Colloidal graphite powder

Colloidal graphite is formed by uniformly dispersing graphite particles less than 2μm in organic solvent. Colloidal graphite is a black silky viscous suspended liquid. Colloidal graphite powder has the properties of high-quality natural flake graphite, has special oxidation resistance, self-lubricity and plasticity under high temperature conditions, and has good electrical conductivity, thermal conductivity and adhesion. It is mainly used in sealing, metallurgical demolding and other industries.

3. Superfine graphite powder

The specifications of ultra-fine graphite powder are generally between 1800 mesh and 8000 mesh. They are mainly used in powder metallurgy release agent, graphite crucible, battery negative electrode, and additive for conductive material.

4. Nano graphite powder

The main specification of nano-graphite powder is D50 400 nanometers. The process of nano-graphite powder is relatively complicated and the yield is low, so the price is relatively high. It is mainly used in anti-corrosion coatings, lubricant additives, grease additives, precision graphite seals and other industries In addition, nano-graphite powder has high application value in scientific research institutions.

5. High-purity graphite powder

As the name implies, high-purity graphite powder has been highly purified, its conductivity is 100 times that of ordinary metals, and it has good lubrication. High-purity graphite powder is mainly used to make conductive coatings and high-strength graphite electrodes.
