si3n4-sic blocks

What is it? Nitride bonded silicon carbide  Silicon nitride bonded silicon carbide uses high grade silicon carbide, metal silicon as the main raw material, according to different application requirements to produce various shapes, after drying, in the vacuum nitriding furnace sintered by high temperature.   1.Characteristic 1. high temperature resistance(up to 1200degree-1600degree) 2. excellent thermal shock resistance 3. oxidation resistance 4. good thermal conductivity 5. acid, alkali corrosion resistance  6. high strength, volume stability 2.application This series of products are widely used in non-ferrous metal(aluminum, zinc) electrolytic cell,metallurgical industry, blast furnace lining, ceramic kiln shelf, pillar, separated flame plate; waste incineration furnace lining and other industries. 3.main parameter
