| Nitride bonded silicon carbide (NSiC) Silicon nitride(Si3N4) melting point is 1900¡æ,hardness is 9,true specific gravity is 3.19k/cm3,thermal conductivity is 15w/m.k,silicon carbide(SiC) is artificial ceramics it's hardness is only less than diamond£melting point is 2600¡æ,true specific 3.21k/cm3;NSiC is a newtype super ceramics that integrate the characteristics of SiC and Si3N4,chemically inert, cold bending strength is 4~8 times of the common refractory, is 2~3 times of the clay bonded SiC, thermal conductivity is 7~8 times of common refractory, is 2 times of clay bonded SiC, is half times of the common refractory, substantial evidence, thermal expansion NSiC has high thermal shock resistance, NSiC products (150x150x15) has no crack that 30 times of 1100¡æ water-cool. the product has series of basic superiority and character such as high thermal shock resistance, high thermal conductivity, resistance of oxidation acid and alkali resistance, high friction tolerance, high bending strength in high temperature resistance of Al,Pb,Sn,Zn,Cu melted metal, high insulance. kiln furniture weight be reduced to 50%, it be able to reduce kiln furniture weight to 50%, load factor has increased by 16%, energy-saving more than 25%,when NSiC replace SiC in the kiln. The plates specifications of our company NSiC products as largely 1800x800x40mm,and provide special-shape product as customers need. FIDONE ceramics has been widely used in production of architectural ware, granite tile, glass ceramics, glass, grinding wheel, metallurgy, nonferrous metals, electronic, chemical industry and circulating fluid bed boiler, power metallurgy, furnace, casting and so on. |
