Tungsten Heating Element And A Sapphire

Sapphire crystal growth mainly tungsten heating element is a heating element

tungsten heating body

made ​​of tungsten . This component is the sapphire furnace production is a central component . There are single-phase and three-phase heater . As a core component of industrial furnaces . Heating element with high efficiency, good temperature uniformity , stable quality, long life characteristics.
Tungsten filament heating element is in the sapphire growth furnace applications a major purpose. There are some other important uses tungsten . Except for a small high-temperature furnace used for heating material , tube heater and the composite material reinforcement , the vast majority are used to make a variety of incandescent and halogen and gas discharge lamp filament electrodes . Mainly used in the production of coiled incandescent filament , the cathode of the power tube and support structure, high temperature furnace heating element and the metal evaporation source of the processing . Thick of tungsten wire,straightening after surface treatment , and cut into a number of rod-shaped , widely used in lighting and electronics industry in glass-metal seal member.

Tungsten heating element is usually made ​​of tungsten strip folded into a middle left blank cover . This cover after power , can produce heat. This is the sapphire growth is an important part of the furnace .
