The most efficient, cost-effective and versatile heating element on the market

Ceramic silicon carbide electric heating elements are designed for high temperature (1800 degree centigrade  to 3000  degree centigrade ) thermal processing applications - for use in furnaces or kilns, as a radiant heat source. As the most efficient, cost-effective and versatile heating element on the market, Ceramic silicon carbide elements are used in many types of industrial furnaces. Since there are no standard sizes and shapes of the products being heated, and no standard dimensions or wattages in furnace designs, Cermet elements are available in a wide variety of sizes and geometries - customized to meet your specific product, process and furnace criteria. specific product, process and furnace criteria.
Advantages of Silicon Carbide Electric Heating Elements Economical, dependable, clean, quiet and safe No fuel availability or storage problems No noxious fuel exhaust to be ducted away Efficiently handle a wide range of products and atmospheres Elements that operate at 600 up to 3000 One of the highest hot:cold ratios in the industry

Chemistry Property

1.Antioxidation Property of Elements
The element start to being oxidized when heat to 800°C in air, and a SiO protect film will be generated in surface of hot zone when temperature get to 1000-1300°C ; cristobalite will be crystallized at 1300°C; the protect film get to a certain thickness when the temperature get go 1500°C which make the oxidation speed being very slowly to stable. if continue to heat to over 1627°C ,the protect film will be damaged and oxidation speed will be more rapid evidently and make the element damaged earlier.
Thought the element will be oxidized very slowly in course of application, it also will make the resistance increased following long time application, this phenonenon calls ageing , in order to lower the ageing speed, we use special technology to spread a protect film on the surface of hot zone in the course of production, which enhance the antioxidant property of element evidently and lengthen the service life.

2.The effects of alkali and alkaline metal oxide to elements.
The alkali and alkaline metal oxide will react with SiC at about 1300°C and generate silicate, which calls alkali-chemical corrosion, and can influence the glowing of element. 

3.The effects to elements from melting metal
Some metals ,such as cobalt, nickel, chrome and so on, can corrade the element in high temperature melting state and affect the service life of element.

Electric Property

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

Notice for using and installing SIC heater:

1. Be protected against damp during storing or installing to ensure the performance ;
2. Divided before assembling. The tolerance of the resistance of each one cannot exceed by 10% each other;
3. Be careful when using and maintaining;
4. When operating the electric furnace at the beginning, the voltage should be increased slowly and cannot be fully loaded at once. Otherwise the larger current will be resulted in the damage of heater. 
5. When heater is damaged and need to be changed, the resistance of new ne should follow the increasing resistance. If many are damaged or resistance increased too much, heater should be changed.
