Application

This high purity white opaque quartz material is mainly used in the field of heat blocking,especially at semiconductor and photovoltaic industries,and is an indispensable component in the semiconductor manufacturing devices.

Characteristics

This high purity white opaque quartz material has excellent surface finish,great heat insulation performance and processing performance close to transparent quartz.This effectively reduces the heat loss outward from the reaction chamber and prolongs the life of the heating components in the devices.
