Crystalline flake graphite???

Application: Cover one layer of crystalline flake graphiteevenly on the surface of the melted copper to isolate from the airand avoid oxidation. The Crystalline flake graphite will alwaysfloat on the melt surface, will not infiltrate or react with themelt or pollute the metal melt. The proper thickness of the layeris normally 12-15mm.

Functions of crystalline flake graphite: good heat resistance,self-lubrication, good heat conduction and electric conductivity,thermal shock resistance and corrosion resistance.
