GD type sic heating element

GD type is the standard element. sic heating element,. It is a high-density sintered silicon carbide element, straight type is available in a large range of diameters and lengths, in two cold end type.

The type heating element adopts special process, is a kind of new heating element saving energy. The main characters: low resistance, high-applied temperature, long service life, save 10--20% power than the common products.

Electrical CharacteristicsThe Yuhao Rod Heating element is a linear type resistance heater that converts electrical energy to heat energy.The heating elements are often referred to as self-bonded, for the lattice structure or bonds that hold the elements together are formed by re crystallizing the silicon carbide at very high temperatures. The elements are manufactured of green silicon carbide. which is classed as an excess electron type semiconductor.The resistance of a silicon carbide element is difficult to measure at roomtemperature due to minor impurities, self-heating, and contact resistance.Also the green silicon carbide has a negative resistance temperature characteristic from, room temperature to approximately 12000F. It turns positive at this point and remains so throughout its normal operating temperature range.
