Product Description
Silicon Nitride Tubes are widely used as temperature measurement sensors. It is important structural ceramic material which is hard and resistant to wear. It is widely used in mechanical hardware, laser semiconductor, petrochemical, automotive, aerospace and other fields.
Silicon Nitride Tubes have good performance on resistant to high temperatures and maintain their strength at temperatures up to 1200°C without loss. It does not decompose until reaching the temperature of 1900°C. In addition, it has amazing chemical resistance, withstanding almost all inorganic acids, and caustic soda solutions up to 30%, as well as many organic acids.
