High Purity Graphite Powder Natural Flake Graphite Powder Graphite Lubricants
High Purity Graphite
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:
- Catalysts in chemical fertilizer industry.
- Additive material for plastics and rubber products.
- Powder metallurgy applications.
- Raw material for graphite foil.
- High temperature coatings.
- Crucibles for melting chemical reagents.
- High quality synthetic diamonds.
