High Thermal Shock Resistance Si3N4 Ceramic Tube

Silicon Nitride (Si3N4) Sealing Pipe & Sealing Valve
High-performance silicon nitride ceramic materials developed for the aluminum industry offer significantly improved thermal and mechanical properties compared to similar products. This innovation brings revolutionary progress to aluminum industrial equipment, particularly in "L-shaped high thermal conductivity submerged heating" applications.
The exceptional high-temperature strength of silicon nitride ceramics ensures long-term durability under frequent operating conditions. Due to the material's brittleness, proper design and installation of lifting transmission devices is essential to avoid mechanical shocks.

Key Advantages
  • The high density, strength, and thermal shock resistance make silicon nitride ceramics the optimal choice for sealing tubes in low pressure die casting applications.
  • Superior wear resistance compared to aluminum titanate and alumina ceramics ensures long-term airtightness of the sealed tube.
