SM9722 Sintered Silicon Nitride Heater Protection Tube Si3N4

Sintered Silicon Nitride Heater Protection Tube Si3N4 Description

Sintered Silicon Nitride (Si3N4) Heater Protection Tube is manufactured via a controlled sintering process that consolidates high-purity silicon nitride into a tubular form. The material exhibits high wear resistance and excellent thermal shock resistance due to its refined microstructure. Its chemical inertness and low thermal conductivity make it suitable as a protective barrier in environments subjected to extreme temperatures and corrosive atmospheres. This engineered tube minimises direct exposure of heater elements to deleterious conditions while maintaining structural integrity.
