Amorphous graphite is the least graphitic of the natural graphites. However, the term "amorphous" is a misnomer since the MATERIAL is still crystalline. Amorphous graphite is found as minute particles in beds of mesomorphic rocks such as coal, slate or shale deposits. The graphite content ranges from 25% to 85% dependent on the geological conditions.
According to size difference and application, we have amorphous graphite powder, graphite grain and graphite briquette as below:
Graphite powder
Size: 80, 100, 150, 200, 325 mesh
Fixed carbon: 70-90%
Application: pencil, battery graphite bearings, foundry MATERIAL, fire-proof MATERIAL, dyestuff and lubrication MATERIALs
Graphite grain
Size: 0-3 mm, 0-6 mm, 0-15mm, 1-5mm, 2-5mm, 1-6mm
Fixed carbon: 70-90%
Application: make steel to increas the carbon, fire-proof MATERIAL, the heat meaterial and electrode compound etc.
Graphite Briquette
It’s to be broken up by raw MATERIAL and then has been gone together with to mix take shape and dry to be the globle structure of certain strength |
