By advanced and unique milling technology, natural flake graphite is grinned to ultra-fine micronized graphite 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 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
- Additive in welding flux
- Water base forging lubricant
- Solid lubricant, blending with mos2, pb, sn, be, added to sinter friction materials
- Antistatic additive in coating, plastic composite products
- Essential component of welding rods and high duty refractory bricks
- Coloring agent which can produce low friction exterior surfaces;
- Heat-spreading stuffing; thermal conductor
- Conductive agent in alkaline battery.
