Special graphites

Special graphites are mainly divided into two categories: extruded graphite and isostatic graphite.

Isostatic (or isotropic) graphite is formed by applying equal pressure from all directions that is produced by applying the same pressure from all directions.

Extruded graphite is produced in an extrusion process. In contrast isostatic graphite, extruded graphite has a coarser grain size and a lower strength but higher thermal and electrical conductivity.

The main fields of application of special graphites are:

  • Graphite machiners
  • Non-ferrous metal industry
  • Semiconductor industry
  • Photovoltaic industry
  • Construction and maintenance of vacuum or inert gas furnaces
  • Heat treatments
  • Carbide industry
  • Aluminum industry
  • Refractory industry
  • Ceramic industry
  • Powder metallurgy
  • Glass industry
  • Precious metals industry
  • Cemented carbide industry
  • Chemical industry
  • Labware
