Introduction of Si3N4 bonded SiC product

Si3N4 bonded SiC as a new type refractory material,is used widely.The applying temperature is 1400 ℃.It has better thermal stability,thermal shock,which is better than plain refractory material and recrystallization SiC.It also has antioxidation,high corrosion resistant,wear-resistantance,high bending strength.It can resist corrosion and scouring,be no polluted in molten metal such as AL,Pb,Zn,Cu ect.

The diameter of Si3N4 bonded SiC thermocouple protection tube is Φ20-50mm,length is 1600 mm.It can be usded in high temperature kiln furnace and all kinds of atmosphere.It also can be used in all kinds of melted liquid.
