Silicon nitride ceramic is an excellent high-temperature engineering material. It has the characteristics of wear resistance, corrosion resistance, high temperature resistance, oxidation resistance, thermal shock resistance, good insulation, and high thermal conductivity. As a new material with the best comprehensive performance, silicon nitride ceramic is widely used in coal chemical industry, new energy, non-ferrous metal casting, metal smelting, aerospace and other fields.
Silicon nitride thermocouple protection tube
Using pure silicon nitride thermocouple protection tubes, the temperature transmission and induction are more rapid and accurate with its high strength and thin thickness. With excellent oxidation resistance and corrosion resistance, the service life of silicon nitride thermocouple protection tube is more than 5-8 times that of NSIC tubes.At the same time, silicon nitride is not infiltrated with the non-ferrous metal melt and it is not easy to form slags and is easier to maintain.
