High quality low price Sic heating element small ceramic heating element

Product Description

1.What’s the Silicon Carbide(Sic) heating element?

The SiC electrothermal element is a rod-shaped non-metallic thermoelectric element which is made of high quality green SiC as the main raw material through processing, high temperature silicification and recrystallization. Compared with metallic electric heating elements, this element has the characteristics of high operating temperature, oxidation resistance, corrosion resistance, long service life, small deformation, convenient installation and maintenance.


2.Applications of silicon carbide heating element

It can be widely used in such applications as sintering and heating elements of ceramics, magnet, glass, metallurgy, refractory, etc.


3.Advantages of silicon carbide heating element

Our silicon carbide electrothermal elements adopt a new hot-cold end production process, with excellent hot-cold end resistance ratio, energy saving, long life, while avoiding the damage to the furnace caused by the high temperature of cold end.


4.The Different Types of silicon carbide heating element

1.) ED(rod)type elements


2.)  DB(dumbbell)type elements



3)  U type elements


4) W(three phase)type elements


5) SC(single spiral)type element


6) SC(double spiral)type elements


7) UX(slot)type elements


5.Physical and Chemical Properties of silicon carbide heating element 

1) Physical properties



2) Chemical Properties

1. Antioxidant property of elements

2. Alkali&alkaline metal oxide will come out alkali-chemical corrosion

3.Melting metal can corrade the element and affect the life.


6.Control of applied temperature&surface load of Mingxin silicon carbide heating elements under different atmosphere



7.Accessories of silicon carbide heating element


8. Notice for using of silicon carbide heating element

1. Heater should be protected against damp during storing or installing to ensure the performance of the heater. 
2. In order to be sure of well-distributed lod of each and groups, heater should be divided before assembling. The tolerance of the resistance of each one cannot exceed by 10% each other. 
3. Heater is hard and brittle, please be careful when assembling and maintaining so as to avoid damage. 
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 one should follow the increasing resistance. If many are damaged or resistance increased too much, heater should be changed.
