The purity of graphite used in semiconductor industry is very high, and its impurity content is not more than 0.001%. The process of producing ultra-pure graphite for semiconductor industry has the following 5 points.

1、Graphite purification furnace with forced air cooling

2、High-power electric furnace

3、Chlorine gas and fluorine gas were mixed to improve the boron removal effect of graphite.

4、Partially purified graphite raw material is adopted.

5、High purity insulation is adopted.
