In the metallurgical industry, tungsten heating elements are considered to be the most suitable heating element for smelting metal, with highest melting point and the lowest vapor pressure. Tungsten heaters are able to function efficiently at temperatures up to 3000 ° C, are practically not susceptible to oxidative reactions in high-temperature environments, have enormous heat resistance (resistance to physical damage during heating) and heat resistance (immunity to aggressive environmental media when heated). The shape and configuration of the tungsten heating element depends on its orientation.

Tungsten heaters also differ in the specifics of using (heater for high heating furnaces, glass melting heater, heaters for growing sapphire single crystals etc.)

A tungsten heating element is a heat source for a single crystal growth equipment. Due to its high melting point and corrosion resistance, tungsten heaters are key to crystal quality control.

Tungsten heater furnaces are used to implement hydrogen, vacuum, and induction technologies.

Among the undoubted advantages of tungsten heaters are high operating temperature (in comparison with composite materials), ability to maintain heat for a long time, lack of need for a long (in time) degassing. The maximum operating temperature of a tungsten heater directly depends on the thickness of the plates of its body and on the chemical composition of the working atmosphere of the furnace.
