Overview
Silicon Nitride Tube is made of high quality silicon nitride ceramic through fine processing. It is an insulator at room temperature with high resistivity and can be used in equipment requiring insulation.
As an excellent high-temperature engineering material, it is most advantageous for its application in the high-temperature industries, so it is mainly used for components such as automotive engines, gas turbines and combustion chambers.
