Morgan Advanced Ceramics Silicon Carbide Nitrite Bonded Pressed Thermal Ceramic
Categories: Ceramic; Carbide

Material Notes: Silicon Nitride bond. The silicon nitride bond phase in these refractories is the key to their superior performance in demanding applications. The Morsil™ nitride bonding system allows nitride bonded refractories to out-perform other silicon carbide based refractories using silicate, alumina silica, and silicon oxynitride and beta silicon carbide bond systems. The alpha silicon carbide crystals impart high thermal conductivity and refractoriness, low thermal expansion and outstanding abrasion/erosion resistance.
