Graphite content above 99.9% graphite called high pure graphite. Is an ideal inorganic non metal crucible boat, crystal furnace heater, EDM graphite, sintering mold, tube anode, metal coating, graphite crucible, semiconductor technology for emission of graphite anode thyratron and mercury arc rectifier tube, the.

High purity graphite has the advantages of small resistance coefficient, high temperature resistance, corrosion resistance, oxidation resistance, good thermal shock resistance, conductivity, small coefficient of thermal expansion, self lubrication, easy machining precision, etc..
