Why Silicon Nitride for Sealing Applications?
Unmatched Performance:
  • Optimal for Low-Pressure Die Casting: High density, strength, and exceptional thermal shock resistance (ΔT 400-500°C) make Si3N4 the premier choice for sealing tubes and valves.
  • Superior Wear Resistance: Outperforms aluminum titanate and alumina ceramics, ensuring long-term airtightness and reducing maintenance frequency.
  • Excellent High-Temperature Strength: Maintains structural integrity under frequent thermal cycling, ensuring prolonged service life.
Design & Installation Note: While silicon nitride offers exceptional strength, its ceramic nature requires careful handling. Avoid large mechanical shocks by ensuring proper design and installation of lifting and transmission equipment.
