High Purity Natural Graphite Flakes Price 350 Expansion Rate Expandable Graphite Powder For Fire Additives
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 is widely used in advanced refractory materials and coatings in the metallurgical industry, military industrial pyrotechnic material stabilizers, pencil leads in light industry, carbon brushes in the electrical industry, electrodes in the battery industry, Fertilizer industry catalyst additives, etc.
