Silicon Nitride Ceramic

Silicon Nitride Ceramic Stopper Tubes (Valves) are ideal for various applications due to their high density, high-temperature strength, and thermal shock resistance. Compared to aluminum titanate and alumina ceramics, silicon nitride ceramics offer superior abrasion resistance, ensuring long-term impermeability. Their high-temperature strength guarantees stable operation under frequent use, while their non-wetting property minimizes slag and molten aluminum contamination.
