Performance And Application Of Silicon Nitride Bonded Silicon Carbide Bricks

Silicon nitride-bonded silicon carbide bricks refer to refractory products made of SiC and Si as raw materials and fired by nitridation. This product first appeared in the late 1960s. It is characterized by Si3N4 as a binder, excellent mechanical properties, thermal stability, and chemical stability, and is widely used in high-temperature industrial fields.

In terms of performance, silicon nitride bonded silicon carbide bricks have high strength, high hardness, excellent wear resistance and corrosion resistance, as well as good thermal shock resistance and high-temperature stability. Its low thermal expansion coefficient can adapt to dimensional changes in high-temperature environments. In addition, silicon nitride-bonded silicon carbide bricks have good thermal conductivity, can effectively transfer heat, and improve the thermal efficiency of the equipment.

In terms of application, silicon nitride-bonded silicon carbide bricks are mainly used in high-temperature industrial fields such as high-temperature furnaces, ceramic product firing, and high-temperature chemical reaction vessels. It can work stably for a long time at high temperatures and does not require frequent maintenance and replacement. In addition, silicon nitride-bonded silicon carbide bricks can also be used to manufacture precision devices such as high-temperature sensors and heat exchangers.

Its excellent performance and stability make it an ideal material choice in the field of high-temperature industry. With the continuous development of science and technology, the performance and application fields of silicon nitride combined with silicon carbide bricks will continue to expand and improve.

In short, silicon nitride combined with silicon carbide bricks is a new type of refractory material with excellent performance and high application value, which plays an important role in the field of high-temperature industry. Its emergence provides new possibilities and opportunities for the development of high-temperature industry.
