Specifications and Product Details:

1Production Process: Made into blank, silicided under high temperature and re-crystallized.

2Usage: It is widely used in various high temperature laboratory furnace and other electric heating devices, such as in the industries of magnet, ceramics, power metallurgy, glass, and metallurgy.

3Character: Higher temperature, antioxidation, anticorrosion, increasing temperature fast, low coefficient of thermal expansion and so on.

Gun-type silicon carbide using the industry and attention.Gun-type silicon carbide material is designed for glass bowl at the heating channel designed to feed the special type of silicon carbide, its features are: heat, heat radiation uniformity, good mechanical properties, the use of safe operation simple.

The linear expansion coefficient,heat conductivity and specific heat of element will change along with temperature change .And the relational data are the follows:

SIC heating elements has rather large specific resistance .when it is heated in air and the surface temperature of the hot zone reaches 1050°C,it's resistance rate is 600-1400 mm2/mm ,its resistance value changes as the temperature rises. From room-temperature to 800°C is negative value ,over 800°C is positive value nature curve.

The key factor to the optimum servece life of the element is to select the surface load of the element correctly according to the furnace construction,atmosphere and temperature.Below figure shows the relation between fumace temperatures,element temperature and element surface load under the condition that the element radiation isn’t obstructed.
