Vacuum High Temperature Carbon Graphite Heater

The vacuum high temperature carbon graphite heater is an efficient and stable heating device, which is mainly used in high temperature scenes under vacuum or inert gas protection. The graphite heater is made of carbon graphite material and has the characteristics of high temperature resistance, low thermal expansion coefficient and high thermal conductivity. At the same time, it has strong chemical stability and is not easy to react with most substances.

In vacuum and high temperature environments, its typical applications include:

1. Material heat treatment: Graphite heaters can be used for sintering, annealing and purification of semiconductors, ceramics and metal materials. Use in a vacuum environment can avoid oxidation, and the uniform heating characteristics of carbon graphite can ensure process consistency.

2. Crystal growth: Carbon graphite heaters can be used for the preparation of sapphire single crystals. Its use can achieve the purpose of maintaining high temperature stability for a long time. Carbon graphite heaters fully meet the thermal shock resistance.

3. Vacuum coating: Carbon graphite heaters can be used in PVD (physical vapor deposition) equipment to provide the high temperature required for the evaporation source while avoiding contamination of the coating material.

The graphite heater has a flexible structural design and can be made into rods, tubes or plates to meet the needs of different equipment. The disadvantage is that it is easy to wear out in an oxidizing atmosphere, so it needs to be strictly isolated from oxygen. The life can be further improved by optimizing the purity of graphite or coating protection (such as SiC).
