High-performance silicon nitride ceramic materials developed for the aluminum industry offer significantly improved thermal and mechanical properties compared to similar products. The "L-shaped high thermal conductivity submerged heating appliance" represents revolutionary progress for aluminum industrial equipment.

Special structural parts requiring exceptional thermal shock resistance represent a key growth area for silicon nitride ceramic materials. In applications involving high temperatures, strong corrosion resistance, and extreme wear resistance, silicon nitride ceramics are increasingly replacing materials such as cemented carbide, alumina, zirconia, and silicon carbide.
