Product Description

Product Description

SiC heating element is a type of non-metal high temperature heating device. These SiC productsare made from fine quality green silicon carbide as its main raw material. The raw material is made first in to a blank, followed by high temperature silication and recrystallization, and becomes high quality stick shaped SiC electric heating devices. Compared with metal electric heating material, this type of non-metal elements is featured of high operation temperature, anti-oxidization, long service life, little deformation, easy installation and maintenance. Because of these advantages, SiC electric heating elements is widely used in various industries that require high temperature electric furnaces and heating devices.
 
Products specification: Rod type, U type, W type (Three Phase type), Solid Rod type, Spiral type, 5 piece type (dual hot zone). Sizes are available from Dia 12mm, 14mm, 16mm, 18mm, 20mm, 25mm, 30mm, 31.7mm (1.25inch), 35mm, 38.1mm (1.5 inch), 40mm, 44.4mm (1.75 inch) to 54mm (2.125 inch) for all types.

 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
