Isostatic Graphite
Isostatic Graphite
Formed by means of CIP (cold isostatic pressing) technique, isostatic graphite is characterized by its homogeneous structure and excellent isotropic electrical, thermal and mechanical properties. Sometimes it is purified in special-designed graphitization furnace to remove non-carbonaceous impurities. It is widely used in a variety of industrial and scientific engineerings as a structural and/or functional material.
Applications
Molds in continuous casting systems for making shaped steel, cast iron, copper;
Sintering molds for cemented carbides, diamond tools and electronic components;
Molds for making shaped glass;
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 for production of manganese dioxide, metallic magnesium and rare metals;
And so on.
