Product Description
Silicon carbide heating element are made by adopting special match and advanced technical. It is featured of lower resistance at cold end, uniform at hot zone, superior anti-oxidization, low corrosion, little deformation, low creep, strong radiation, quick rising temperature, easy installation and maintenance. Silicon carbide heating elements is widely used industries that require high temperature electric furnaces and heating devices. These typical applications include metallurgy, machinery, chemical, semiconductor, ceramics glass, food textile etc.
SIC heating element can usually make use for furnaces or kilns which temperature is from 6000 C -16000C. The max temperature can up to 16500C. Silicon carbon heating elements have all kinds of specifications, super quality and lower price. Our products have been well recognized in China. We are gaining market share overseas, such as USA, German, France, Ialy, Russia, South Korea, India, Pakistan, Brasil etc.
Product Specification
Our products include all kinds of silicon carbide heating element, such as dumbbell type, straight rod type, "U" type (slot type), gun type, H type, GDS type (three- phase ), and single spiral and double spiral type etc.

Chemistry Property
1.Antioxidation Property of Elements
The element start to being oxidized when heat to 800°C in air, and a SiO2 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.
