Purified graphite electrode for high purity quartz crucible
The semi-transparent quartz crucible made by the arc method is an essential material for drawing large-diameter mono-crystal silicon and for the development of large-scale integrated circuits. Today, in the semiconductor industry and the photovoltaic mono-crystal silicon industry, the large-diameter quartz crucibles have generally replaced small transparent quartz crucibles with the advantages of high purity, high temperature resistance, high dimensional accuracy, good heat preservation, energy conservation, and stable quality.
In the preparation of quartz crucible by arc method, the purified graphite electrodes have the advantages of high temperature resistance, electrical conductivity, high purity, etc., and are widely used.
