Crystal silica is made from high grade quartz through specialprocess. The product has high purity and controllable particle sizedistribution.

The main characters of crystal silica are as follows:

• high electric insulation property.
• High hardness, good wearable.
• Excellent chemical stability. It only can react withhydrofluoric acid and strong alkali.
• Better thermoconductivity than other silica.
• Good whiteness
