High Purity Graphite

Specifications
High purity graphite was made from reaction of flake graphite and various kinds of acids. Acid removes the impurities inside flake graphite, and boosts the purity to 99-99.98%.

It has the advantages of high temperature resistance, corrosion resistance, thermal shock resistance, self-lubricating, and small resistivity, etc.

Our Regular Flake Graphite is the right solution for:
  • Battery applications.
  • Catalysts in chemical fertilizer industry.
  • Additive material for plastics and rubber products.
  • Carbon brushes.
  • Powder metallurgy applications.
  • Raw material for graphite foil.
  • Fuel cell applications.
  • High temperature coatings.
  • Crucibles for melting chemical reagents.
  • High quality synthetic diamonds.
