abrasion and high temperature resistance silicon nitride ceramic heater protection tube
Silicon nitride is one of the hardest ceramics but also one of the most resistant. Si3N4 is mainly used in severe environments which combine extreme temperatures with abrasive and/or corrosive medium. Silicon nitride can be of different grades : sintered, hot pressed or reaction bonded.
1.High temperature resistance,corrosion resistance,and non-immersion with molten metal
2.The thermal shock resistance and not falling, not burst
3.Extremely low coefficient of thermal expansion
4.Anti-oxidation,long service time
5.Could made according to customers’specification
