Properties And Applications Of Silicon Nitride Bonded Silicon Carbide Brick
silicon nitride bonded silicon carbide brick (silicon nitride bonded silicon carbide brick) refers to the use of SiC and Si as raw materials, by nitriding fired refractory products. The product first appeared in the late 1960s, which is characterized by Si3N4 as a binder, has 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 brick has high strength, high hardness, excellent wear resistance and corrosion resistance, as well as good thermal shock resistance and high temperature stability. Its coefficient of thermal expansion is low, and it can adapt to the size change in high temperature environment. In addition, silicon nitride combined with silicon carbide brick has good thermal conductivity, can effectively transfer heat, improve the thermal efficiency of the equipment.
In terms of application, silicon nitride combined with silicon carbide bricks are mainly used in high-temperature furnace, ceramic product firing, high-temperature chemical reaction vessels and other high-temperature industrial fields. It can work stably at high temperatures for a long time and does not require frequent maintenance and replacement. In addition, silicon nitride combined with silicon carbide bricks can also be used to manufacture precision devices such as high temperature sensors and heat exchangers.
Its excellent properties and stability make it an ideal material choice for high-temperature industrial applications. With the continuous development of science and technology, the performance and application fields of silicon nitride bonded silicon carbide bricks will continue to expand and improve.
In short, silicon nitride bonded silicon carbide brick is a new refractory material with excellent performance and high application value, and has an important position and role in the field of high temperature industry. Its emergence provides new possibilities and opportunities for the development of high-temperature industry.
