Isostatic Pressing Graphite

Isostatic Pressing Graphite

Isostatic graphite is an ultra-fine grain graphite used for applications where the mechanical properties of other fine grain graphites are inadequate.

The term "isostatic graphite" stands for isostatically molded graphite. This means that the raw material mixture is compressed into rectangular or round blocks in a so called Cold-Isostatic-Press (CIP).

Compared to other technologies such as extrusion or vibration molding, this technology can produce the most isotropic form of artificial graphite. In addition, isostatic graphite generally tends to have the smallest grain sizes of all artificial graphites.

Typical properties of isostatic graphite

· Extremely high thermal and chemical resistance

· Excellent thermal shock resistance

· High electrical conductivity

· High thermal conductivity

· Increasing strength with rising temperature

· Easy to machine

· Can be produced with very high purity < 5 ppm

Applications where isostatic graphite is used

Nowadays isostatic graphite represents a large part of the fine-grain graphite market and has found applications in over 30 different industries, from nuclear and metallurgical applications to semiconductor, solar, continuous casting, EDM and many others.
