Product Description

 

Product Description

GC type Dumbbell rod thick end Type SiC Silicon Carbide electric resistance furnace industry factory manufacturer lab heater Heating Element Sic Heating Rod

 

Laboratory electric (GC) dumbbell shape sic heating element

SiC heating element is made from the high purity green hexagonal silicon carbide material. Make into blank according to a certain formula. Then through 2200ºC high temperature silicatization recrystallization sintering, non-metallic high temperature electric heating element is finished. The normal operating temperature in the oxidizing atmosphere can reach 1450ºC, and the continuous use can reach more than 2000 hours -3000 hours.

 

Features

 

1. Withstands as high as 1600°C (surface temperature),

2. Generates high heat output per unit surface area, approximately 5-10 times than the output of Nichrome wire,

3. High strength and excellent shock resistance.

4. Heat source is free of noise and air pollution.

5. Efficiently handle a wide range of products and atmospheres without any protection atmosphere.

Chemistry Property

GC type Dumbbell rod thick end Type SiC Silicon Carbide electric resistance furnace industry factory manufacturer lab heater Heating Element Sic Heating Rod

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
Silicon carbide (SiC)  heating element/heater 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.
