氧氮化硅结合碳化硅窑具 Silicon oxynitride bonded silicon carbide kiln furniture

    The silicon oxynitride bonded silicon carbide kilnfurniture is silicon carbide composite kiln furniture with SiC as the maincrystal phase and Si2N2O as the main bonding phase. It isprepared using silicon carbide and metallic silicon powder as main startingmaterials, firing at about 1500 by high temperature nitridation reaction. Characterized by high strength,good oxidation resistance and good thermal shock resistance, it has been usedin industries of sanitary ceramics, electric porcelain, abrasive materials andtools, and high-tech industrial ceramics since 2002, and has been applied inabove 80 related plants in China and overseas with good performance. It wasawarded the Third Prize of Metallurgical Science &Technology Progress in HenanProvince andNational Key New Products in 2006.
