Physical Properties of Resistive Graphite Heaters

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 heating source of the furnace, its quality directly affects the performance and operating cost of the furnace. Xingtai Lingte Technology Co., Ltd. has been engaged in the processing of the graphite thermal field of the single crystal furnace for many years. Our common graphite heaters are resistive.

Most vacuum furnaces use resistance heating methods, and metal materials are used in the previous heater selection, and various design forms of heaters are carried out according to the size of the furnace. Graphite is the preferred material for heaters because graphite has excellent characteristics such as high temperature resistance, high thermal conductivity, thermal shock resistance and so on.

With the improvement of graphite material properties and processing technology, more and more graphite heaters have been applied to heat treatment and brazing furnaces, and the number has exceeded that of molybdenum heaters. The main advantages of graphite heaters are: lightweight design, rich shapes, long-lasting durability and easy maintenance.
