【Graphite Powder】Applications of Different Mesh Sizes

The grade of graphite powder refers to its particle size, which is typically expressed in mesh (μm). Based on different mesh sizes, graphite powder can be classified into various specifications, including but not limited to the following:

1. 100 mesh: Coarsest particles, mainly used in molten iron casting, precision ceramics, and bearing materials.

2. 150 mesh: Relatively coarse, applicable for refractory materials, graphite products, and lubricants.

3. 200 mesh: Medium granularity, used in carbon products, bearing materials, and paints.

4. 325 mesh: Primarily used for refractory materials, conductive materials, wear-resistant materials, lubricants, high-temperature sealing materials, and graphite emulsions.

5. 600 mesh: Used in powder metallurgy, friction materials, lubricants, pencils, pigments, handicrafts, and electrode production.

6. 800 mesh: Applied in conductive materials, lubricants, refractory materials, high-temperature materials, pencils, pigments, and electrode manufacturing.

7. 1200 mesh: Mainly used for high-purity graphite products in the electronics industry, as well as in lubricants, pencils, pigments, and electrodes.

8. 2000 mesh: Suitable for high-purity graphite products, high-purity graphite in electronics, graphite paper, lubricants, pencils, pigments, and electrodes.

In general, a higher mesh number indicates finer particle size, making it more suitable for precision applications. Different applications require specific levels of purity, particle size, and morphology; therefore, the appropriate graphite powder specification should be selected based on actual requirements.
