Product Details

STA high performance silicon carbide ceramic sheath for alumina liquior

Silicon Nitride Bonded silicon carbide sheath

Product Description

Si3N4 bonded SiC ceramic refractory material, is mixed with high pure SIC fine powder and Silicon powder, after slip casting course, reaction sintered under 1400~1500°C. During the sintering course, filling the high pure Nitrogen into the furnace, then the silicon will react with Nitrogen and generate Si3N4,.Si3N4 bonded SiC material is composed of silicon nitride (23%) and silicon carbide(75%) as main raw material,mixed with organic material,and shaped by mixture, extrusion or pouring,then made after drying and nitrogenization.
