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