Isostatic graphite:
a synthetic graphite’s variant

The “isostatic graphite” refers to the graphite isostatically created: this means that the mixture of raw materials is pressed into rectangular or round blocks in a so-called cold isostatic press (CIP). Compared to other processes, such as extruding or vibration moulding, this technology can produce a more isotropic kind of synthetic graphite.

In addition, the isostatic graphite has usually the smallest grain sizes of all the synthetic graphite. The isostatic graphite nowadays represents the large majority of the market of this fine-grain material and it has found application in over 30 different sectors: from nuclear and metallurgical applications to semi-conductor devices, solar industry and many others.

Among the isostatic graphite’s applications, there are billets, conveyor belts, pipes and melting of various metals including aluminium, brass, bronze, (grey and ductile) iron, nickel silver (alpaca), copper-nickel, metal precious alloys, silver, gold and various parts used in electroerosion sector.

Typical properties of the isostatic graphite

  • Very high heat and chemical resistance
  • Excellent thermal shock resistance
  • High electrical conductivity
  • High thermal conductivity
  • Increased strength with increasing temperature
  • Easy to work
  • Can be manufactured with very high purity (< 5 ppm)

Isostatic graphite’s applications

  • Aluminium’s treatment
  • Compound semiconductor and LED
  • Continuous casting
  • Electric-discharge machining
  • Glass and refractory industries
  • Semiconductor photovoltaic
