In the production process of quartz crucibles, it is most common to use the arc generated by the graphite electrode discharge to heat and melt the quartz crucible. Traditionally, three graphite electrodes are generally used as a group. Since the quartz crucible is an important accessory for solar and semiconductor single crystal silicon production, its purity requirements are relatively high, so the graphite electrode for quartz crucible must also be of high purity. We can supply graphite electrode and mold with purity less than 50ppm.

Materials suitable for graphite mold

Product Description

For the quartz crucible used in the crystal drawing of monocrystalline silicon, graphite is used as a mold and graphite electrode in the manufacturing process. It makes full use of the characteristics of graphite, such as high temperature resistance, non wetting, conductivity and so on.

Product Features

Conventionally, we use high-purity graphite materials to produce graphite electrode for quartz crucible. High quality graphite electrode is very helpful to improve the product qualification rate of quartz crucible and reduce the quality defects on the inner surface of quartz crucible.

Our company uses extruded graphite rod with high strength and low ash content to process graphite electrode for quartz crucible. This graphite electrode has high purity and excellent conductivity, and has been widely recognized by customers at home and abroad.

Graphite machining process

SHJ has a variety of mechanical processing production lines, customized processing according to drawings, while meeting customers' different precision requirements, select the most cost-effective processing technology with the shortest processing time.
