The semiconductor industry is a new scientific and technological field that has received great attention in recent years. The development of semiconductor technology is inseparable from the application of graphite materials in the semiconductor industry. In these miconductor industry, high-purity graphite materials are mainly used to manufacture graphite heating systems for single crystal furnaces, electronic component sintering molds, insulator sintering molds, and thyristor sintering molds, among others. Among the graphite products used in single crystal furnaces, the following are the most common:

1. Graphite heaters. The requirements for the heating system in a single crystal furnace are to provide sufficient heat to quickly melt silicon, germanium, etc., and to be able to fine-tune and adjust the temperature conveniently. Therefore, heating is usually done using resistance and high-frequency heating methods.

2. Graphite electrodes, graphite pillars,and other graphite parts. In addition to using high-purity graphite to manufacture heaters in a single crystal furnace, it is also used to manufacture graphite electrodes, graphite pillars, graphite insulation covers, graphite insulation covers, graphite seed crystal holders, graphite slag trays, and graphite supports.

3. Graphite insulation cylinders.
