Isostatic Graphite
 Isostatic Graphite |
Product Description
Electrodes for EDM; heating elements, heat shields, crucibles, boats for pulling monocrystalline silicon or optical fibers.
Formed by means of cold isostatic pressing (CIP) 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 various industrial and scientific engineerings as a structural and/or functional material.
