Products details

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 engineering 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 & rare metals and etc.
 

1. Graphite plate and grid plate for emission electron tube, thyratron and mercury arc rectifier
2. Graphite boat container, crucible and heating element for semiconductor technology, and heater for single crystal furnace
3. Graphite container for metal gasification, mold for continuous casting, graphite mold plate for pressure sintering, graphite electrode for electrical discharge machining, etc.
