Main material is calcined coke (after grinding twice with lowash) and coal tar pitch as binders , via burdening, mixing, moldingextrude, baking, (dipping), graphitizing (above 2300 degrees), andmachining to form. This product have good property of thermalresistance, high electric and thermal conductivity, high lubricityand excellent mechanical character. Widely used in electron,machinery, chemical industry, etc. Appling as rectifier graphiteanode, mold for electronic agglomeration, constantly castinggraphite crystallized, accurate casting, the melting ofsemiconductor and rare metals, graphite crucible, mechanical sealin some fields as chemical industry, electrospark machiningdischarge anode, etc.
