Isostatic Graphite
lsostatic pressure isotropic graphite is made of high-quality asphalt coke, petroleum coke as raw material and pitch as binder by grinding,batching,mixing,secondary grinding, isostatic pressing molding,baking,impregnation,graphitization,purification and other processes has the characteristics of good isotropic,fine and uniform structure, high mechanical strength, good high temperature resistance, strong chemical corrosion resistance, good electrical and thermal conductivity and excellent machining performance, widely to be used in solar photovoltaic,semiconductor,metal continuous casting, precious metal smelting, and other industries.
Applications
All kinds of molds in continuous casting systems for making shaped steel, cast iron, copper.
Sintering molds for cemented carbides, diamond tools and electronic components.
Molds for the glass industry.
Crucibles for melting precious metals or alloys.
Electrodes for EDM.
Heating elements, heat shields, crucibles, boats in furnaces for pulling monocrystalline silicon or optical fibers.
Anodes produce manganese dioxide, metallic magnesium and rare metals.
