High-purity graphite can be used in the solar photovoltaic industry and is the core part of the thermal field vacuum resistance furnace. Since the graphite heater is the main heat source of the furnace, its quality directly affects the performance and operating cost of the furnace. The company has been engaged in the processing of single crystal furnace graphite thermal field for many years. Our common graphite heaters are all resistive.

Most vacuum furnaces use resistance heating methods. In the previous heater selection, metal materials were used. Various designs of heaters were carried out according to the size of the furnace. Graphite is the preferred material for heaters because it has excellent characteristics such as high temperature resistance, high thermal conductivity, thermal shock resistance, etc.

The main advantages of graphite heaters are: light design, rich shapes, durability and easy maintenance.
