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 90% to 99.9%, and the particle size is adjustable, from 2 micron to 18 micron at D50. Key features: Stability & strength at high temperatures (up to 3200oC); 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) additive in coating; 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.
