Silicon nitride combined with silicon carbide brick is a high hardness refractory material with excellent wear resistance, high high-temperature strength, strong resistance to high-temperature creep, strong slag corrosion resistance, and good seismic stability. In addition, the product has good oxidation resistance, low thermal expansion coefficient, and higher thermal conductivity. Therefore, it is not easy to generate thermal stress during high-temperature use and has a long service life
Due to the excellent mechanical and chemical stability properties of silicon nitride combined with silicon carbide bricks, they are widely used in large-scale ironmaking blast furnaces, non-ferrous metal smelting, aluminum electrolytic cell sidewall materials, ceramic kiln furniture, etc
