Hot rods are made from quality SIC, which was also added to some additives according to the materials proportion. Silicon carbide electric heating elements are sintered non-metallic products of round section rod or tubular form.
Compared with metallic heating elements, they have a series of characteristics such as high temperature tolerance, oxidation and corrosion resistance, maintaining and setting-up conveniently and guarantee for a long life. Therefore, they are widely used in electronic and magnetic material, metallurgy, and machine industries

Electrical Characteristics
The 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 ****0F. It turns positive at this point and remains so throughout its normal operating temperature range.
