Graphite material for diamond tools sintering

Details

 

The graphite mould is made of high purity graphite material, has excellent electric & thermal conductivity.

Graphite mould that made of high quality graphite mould has below property in pressure sintering of diamond tools:

  1. High density, 1.80-1.90 g/cc, excellent physical performance.
  2. Resistance to high temperature, excellent thermal conductivity.
  3. Resistance to corrsion of acid and alkali.
  4. Long service life.
  5. If pressure temperature increase to 1350 – 1450℃, required unit pressure will be reduced to 67-100 kgf/cm (1/10 pressure of cold press).
  6. Forcing and heating could be proceed in one procedure, compact sintering body could be obtained in short time.
