What are the types of graphite powder?

Graphite powder has chemical stability, can resist acid, alkali, and corrosion from organic solvents. Due to the excellent properties of graphite, its industrial applications are becoming increasingly widespread. And there are many classifications of graphite powder, which can be divided into the following five categories according to different uses:

1.Flake graphite powder

The use of flake graphite powder is extensive, and it is also the raw material for processing into other graphite powders. The specifications of flake graphite powder range from 32 mesh to 12000 mesh. 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, sanding, molding and high-temperature metallurgical materials.

2.Colloidal graphite powder

Colloidal graphite is formed by evenly dispersing graphite particles below 2 μ m in organic solvents. Colloidal graphite is a black, viscous suspension liquid. Colloidal graphite powder has excellent properties of natural flake graphite, with special oxidation resistance, self-lubricating and plasticity under high temperature conditions, as well as good conductivity, thermal conductivity and adhesion. It is mainly used in industries such as sealing and metallurgical demolding.

3.Ultra fine graphite powder

The specifications of ultrafine graphite powder are generally between 1800-8000 mesh, mainly used as a release agent in powder metallurgy, in the production of graphite crucibles, as a negative electrode for batteries, and as an additive in conductive materials.

4.Nano graphite powder

The main specification of nano graphite powder is D50 400 nanometers. The process of nano graphite powder is relatively complex and the production rate is low, so the price is relatively high. It is mainly used in industries such as anti-corrosion coatings, lubricant additives, grease additives, graphite seals, etc. In addition, nano graphite powder also has high application value in scientific research institutions.

5.High purity graphite powder

High purity graphite powder, as the name suggests, has undergone a high degree of purification. Its conductivity is 100 times that of ordinary metals and it has good lubricating properties. High purity graphite powder is mainly used to make conductive coatings and high-strength graphite electrodes.

The above are the five major types of graphite powder. Do you all understand? Choose the appropriate type according to the purpose, so as to play a more effective role!
