Nitride Bonded Silicon Carbide Brick is characterized by high high temperature strength, abrasion resistance, corrosion resistance and resistance to molten metal erosion. We offer high quality Nitride Bonded Silicon Carbide Brick with wholesale & sales at factory price.
Silicon carbide nitride brick is a kind of high-performance refractory brick mainly composed of two compounds of silicon nitride and silicon carbide. Silicon nitride and silicon carbide bricks are widely used in high-temperature equipment in metallurgy, construction, iron and steel, electric power, chemical industry, ceramics and other industries because of their high-temperature strength, abrasion resistance, corrosion resistance, and resistance to the erosion of molten metals.
High temperature strength
Silicon carbide nitride firebricks have higher high temperature strength than traditional refractory materials and can withstand extreme environments such as high temperatures and high pressures.
The high hardness of silicon carbide nitride bricks can withstand mechanical abrasion and impact.
Silicon carbide nitride refractory bricks have high resistance to corrosive substances such as acids, alkalis and oxides.
Resistance to molten metal erosion
Silicon carbide nitride bricks can withstand the erosion of molten metal and are not easy to melt and soften.
High density and low coefficient of thermal expansion
Silicon Carbide Nitride Refractory Brick has high density, so it has better compression resistance, and at the same time, it has low coefficient of thermal expansion, so it is not easy to have thermal stress and rupture.
High temperature resistance
Silicon Carbide Nitride Firebricks have a wide range of operating temperatures, and can withstand high temperature environments up to 1800℃.
Silicon carbide nitride bricks are chemically stable and can maintain stable performance for a long time.
Silicon Carbide Nitride bricks are less dense than traditional refractory materials, making them easier to handle and install.
Silicon Carbide Nitride Refractory Bricks are mainly used in metallurgical industry for lining of high temperature equipment, such as blast furnace, converter, electric arc furnace, ladle and so on. Silicon carbide nitride bricks can withstand high temperature, high pressure, corrosion and other harsh environments, and protect the equipment from molten metal and other chemical substances.
Nitrided silicon carbide bricks can be used to manufacture reactor, heating furnace, heat exchanger and other parts of chemical equipment to withstand high temperature, corrosion and other harsh environments.
Silicon Carbide Nitride Firebricks can be used in the masonry of high temperature, high pressure equipment lining and flue and other parts in the power industry, such as boilers and chimneys of coal-fired power plants.
Nitrided silicon carbide firebricks can also be used in the lining of high-temperature equipment in the ceramic industry, such as kiln hearths and flues.
