Natural Flake Graphite is produced from the natural ore mainly excavated in Shandong, Heilongjiang and Inner Mongolia through floatation process. It has excellent conductivity and lubrication properties and is highly resistant to oxidation and chemical agents.
Expendable Graphite is manufactured by treating highly crystalline natural flake graphite with a mixture of sulfuric acid and certain other oxidizing agents which aid in “catalysis“ of the sulfate intercalation.
