Product Description

SiC heating element is a type of non-metal high temperature resistances heating elements. The elements are made from fine quality a-SiC as its main raw material. The raw material is first made first in to a blank, followed by high temperature silication and recrystallization, and becomes high quality tube shaped heating elements. 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 heating elements is widely used in various industries that require high temperature electric furnaces and heating devices. These typical applications include electronics, magnetic materials, powder metallurgy, ceramics, glass, metallurgy and machinery.
 

Name:	SiC Heating Element
Shape:	ED, SC, SCR, Dumbbell, U, W and other special shape
Used temp:	Up to 1400C
Product process:	Made into blank, silicided under high temperature and re-crystallized.
We can produce various specifications SiC heating element according to your need.
Advice of using the element 1) In order to keep furnace temperature and the charges uniform of each element, before installation resistance distribution must be carried. 2) As the element is very brittle, be careful while install and maintain to avoid any damage. 3) When start to operate the furnace, raise voltage slowly and gradually, never give full load at one time.   Character High-applied temperature, anti-oxidization, anti-corrosion, long service life, little deformation, easy installation and maintenance.   Application Used in various high temperature electric furnaces and other electric heating devices, such as in the industries of magnet, ceramics, metallurgy, glass, and machinery.

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.
