Si3N4 bonded SiC ceramic refractory material, is mixed with high pure SIC fine powder and Silicon powder, after slip casting course, reaction sintered under 1400~1500°C. During the sintering course, filling the high pure Nitrogen into the furnace, then the silicon will react with Nitrogen and generate Si3N4,So Si3N4 bonded SiC material is composed of silicon nitride (23%) and silicon carbide(75%) as main raw material,mixed with organic material,and shaped by mixture, extrusion or pouring,then made after drying and nitrogenization.
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 and recrystallized SiC.It also has antioxidation,high corrosion resistant,wear-resistantance,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.
