Product Description Product DescriptionNitride Bonded Silicon Carbide Brick is a high-grade refractory material with silicon carbide sand as the main raw material and silicon nitride as the binding phase. Since SiC and Si3N4 are covalent bond compounds, sintering is difficult, and they are usually prepared by reaction sintering in industrial production. Using SiC as aggregate, adding metal silicon powder, choosing reasonable particle grading, kneading system and forming process, the dried green body is fired in a special firing equipment in a nitrogen atmosphere. During the firing process, the generated Si3N4 (matrix binding phase) is off-white crystal, which can effectively combine SiC particles (aggregate) to form a spatial network structure, so that bricks have incomparable characteristics with other refractory materials.Features of Nitride Bonded Silicon Carbide BrickNitride Bonded Silicon Carbide Brick not only has the characteristics of high density, high strength, good thermal shock stability, high load softening point, good thermal conductivity, high resistance value, etc., but also has excellent resistance to cryolite, aluminum fluoride, sodium fluoride and calcium fluoride, etc. Melt corrosion and oxidation resistance.Applications of Nitride Bonded Silicon Carbide Brick1. Building and sanitary ceramics industry. At present, in the firing of ceramic products, most of them use roller kilns to fire sanitary ceramics and wall and floor tiles, and the rollers of roller kilns are basically made of silicon nitride and silicon carbide.2. Household ceramics industry3. Electric porcelain and electronic ceramic industry4. Aluminum smelting, copper, zinc and other industries5. Steel-making and steel-rolling industry. The application of new technologies and processes for steel-making has put forward higher requirements for refractory materials used in ladles, and the lining of ladles has changed from the high-alumina bricks that dominated in the past to better corrosion resistance. The material silicon nitride bonded silicon carbide material6. Ironmaking industry. In recent years, silicon nitride combined with silicon carbide bricks for blast furnaces has developed rapidly, and about 61% of blast furnaces abroad have adopted them, especially 68% of large blast furnaces with a hearth diameter of 12-15m.7. Metal heat treatment industry, etc.BrandPropertiesNtri-SiC BrickOxide-SiC Brick 90Oxide-SiC Brick 80HA-SiC BrickBulk Density (g/cm3)2.652.52.42.65Apparent Porosity (%)16171822Cold Crushing Strength (MPa)1301008090Refractoriness Under Load (oC) @0.2MPa1700165015501680Thermal conductivity (W/m.k)181514--Chemical Analysis (%)SiC73-81908010Si3N416-25------Fe2O30.30.81.065 Al2O3Main ApplicationsCopper FurnaceAlumina Furnaceceramic kiln shelf panelsIncineration furnaceQ1 : How can you control your quality?A1 : For each production processing, JUCOS have complete QC system for the chemical composition and Physical properties.
