natural graphite powder for pencil lead

详情

By advanced and unique milling technology, natural flake graphite is grinded to ultra-fine powder. We can control the particle size distribution and carbon content. The fixed carbon is from *0% to *9.9%, and the particle size is adjustable, from 1 micron to *8 micron at D*0.

Key features:
Stability at high temperatures (up to ***0^oC);
High conductivity of solid;
Low coefficient of thermal expansion;
Good electrical conductivity;
High resistance to erosion;
Good machinability;
Low friction, self-lubricating ability;
High adsorption of gases and vapours

The microfine/ultra fine graphite is used as
1) additive in welding flux;
2) water base forging lubricant;
3) solid lubricant, blending with MoS2, Pb, Sn, Be, added to sinter friction materials;
4) antistatic additive in coating, plastic composite products;
5) essential component of welding rods and high duty refractory bricks;
6) coloring agent which can produce low friction exterior surfaces;
7) heat-spreading stuffing; thermal conductor;
8) conductive agent in Alkaline battery.
