Coated ED Type Silicon Carbide Rod
1. Antioxidant property of sic heating elements
The sic heating elements start to being oxidized when heated to 800C in air;and Si02 protection film will be generated in surface of hot zone when temperature get to 1000-1300C;Cristobalite crystalized at 1300℃,at 1500℃ the protection film reaches a certain thickness which make the oxidation speed being most slowly and tends to be stable.If continuely heat to over 1627℃,the protection film will be damaged and oxidation speed will be more rapid evidently and make the sic heating elements damaged earlier.
Though the sic heating elements will be oxidized very slowly in course of application,it also will make the resistance increased in use of a long time,this phenomenon is called ageing.In order to lower the ageing speed,we use special technology to coat a protection film on the surface of hot zone in the process of production,which enhance the antioxidant property of sic heating elements obviously and lengthen the service life.
2. The effects of alkali and alkaline metal oxide to sic heating elements
The alkal and alkaline metal oxide will react with SiC at about 1300C and generate silicate,which is called alkali-chemical corrosion,and can influence degree of the sic heating elements glowing.
3. The effects to sic heating elements from melting metal
Some metals,such as cobalt,nickel,chrome and so on ,can corrade the sic heating elements in hign temperature melting state and affect the service life of heating element.
Silicon Carbide Rod Details
1, Silicon carbide heating element is one type of ceramic heating elements,which use six-party high purity green SiC powder as the main raw material.Silicon is recrystallized under 2200C high temperature to form finished materials.The using temperature up to 1450C under oxidation atmosphere,and constant working life up to 2000 hours.It is widely used in various high temperature electric furnaces and othe electric heating devices,such as in the industries of magnet,ceramics,powder metallurgy,glass,metallurgy and machinery,etc.
2, Protech silicon carbide SiC heater element is a kind of nonmetal high temperature electric heating element.It is made of selected super quality green silicon carbide as main material,which is made into blank,silicide under high temperature and re-crystallized. Max temperature 1600 deg C.
