Silicon nitride protection tube

Silicon nitride ceramics possess excellent properties of high thermal stability,antioxidant capacity and good dimensional precision of products.This is essential to detect even tiny temperature differences and permit an effective automatic control loop.Silicon nitride is especially suitable for thermocouple protection tube measuring temperature of molten aluminum for its anti-fusion.In order to guarantee tube's quality,we used the excellent raw material and adopt strict total quality management and advanced techniques.

Silicon nitride protective tube is widely used for non ferrous metal casting.Especially for measuring the temperature of liquid aluminum.
