SiC and Si3N4 have many good physical and chemical properties, such as high mechanical strength, good thermal conductivity, and chemical stability against acid and alkali corrosion. Silicon carbide thermocouple protection tube combine the advantages of Si3N4 and SiC, with high density, high strength, good thermal shock stability, high softening temperature under load, good thermal conductivity, high resistance, not easy to be wet by non-ferrous metals and other characteristics, and has a good resistance to cryolite, aluminum fluoride, sodium fluoride, calcium fluoride and other melt erosion. Nitride bonded silicon carbide tube is a kind of inorganic composite material with great development prospect.
