By advanced grinding technology, we mill natural graphite flakes to be spherical. This grade graphite has low specific surface area(SET) and very high tap density. The tap density is above 1.0g/cc, while the SSA(BET) is from 3.5-8m2/g. The particle size is from 8 micron to 35 micron at D50. Because of its high crystalline structure and high purity, Microspherical Graphite is used as 1) bi-polar plates of fuel battery; 2) electrical conductive agent in carbon brush; 3) pore former in ceramic membrane; 4) heat-spreading materials; 5) filler for carbon and resin composite materials; 6) other electric storage applications such as electric double layer capacitors.
