Supply Capacity

All the material are high purity graphite and fine-grain, as a graphite manufacturer who can provide stable supply for big customer, we have uniform shaped graphite rods and graphite blocks in stock all the time.

Isostatic graphite refers to a graphite material obtained by pressing a high-purity graphite powder in a sealed liquid environment at a normal temperature and transferring the powder by ultra-high pressure. Because the pressure in the liquid is equal on each side, it is called cold isostatic pressing. The shaped graphite has the same performance values in different directions.


XRD's Isostatic graphite products has a series of excellent properties compared to ordinary graphite, indcluding:

Strong Thermal Stability

Low Expansion Ratio

Excellent Chemical Resistance

Excellent Electrical Conductivity and Thermal Conductivity

Good Machinability
