Seven properties of green silicon carbide

Green silicon carbide refractories play a crucial role in high-temperature industrial fields due to their high melting point, excellent erosion resistance, Yuqori issiqlik o'tkazuvchanligi, low coefficient of thermal expansion, yuqori kuch, and good wear resistance.

Properties of green silicon carbide

High melting point and high temperature stability

Green silicon carbide has a high melting point, and refractory materials made primarily from it or as an additive can maintain structural stability for extended periods in high-temperature environments above 1600℃, without easily softening or melting. This makes it an ideal material for the linings of high-temperature equipment such as blast furnaces for ironmaking, aluminum refining furnaces, and waste incinerators, ensuring the long-term stable operation of these furnaces.

Excellent corrosion resistance

Green silicon carbide exhibits strong chemical stability, resisting corrosion from acids, alkalis, salt solutions, and other chemicals. In non-ferrous metal smelting and the steel industry, its lining material effectively resists the erosion of molten metal and slag, extending the service life of equipment.

High thermal conductivity and thermal efficiency optimization

Green silicon carbide has a thermal conductivity far exceeding that of traditional refractory materials. It can rapidly transfer heat at high temperatures, reducing heat loss in kilns.

Silicon carbide as an additive to improve performance

Green silicon carbide can be added as an additive to other refractory materials to improve their high-temperature resistance, corrosion resistance, and wear resistance. Adding green silicon carbide to steelmaking deoxidizers can improve the purity of molten steel; adding green silicon carbide to unshaped refractories can optimize their thermal properties, making them suitable for the repair and casting of high-temperature industrial kilns.

Manufacturing refractory products

Green silicon carbide can be used to produce high-grade refractory materials such as recrystallized silicon carbide products, silicon nitride-bonded silicon carbide components, gas turbine components, and nozzles. These products are widely used in energy, kimyoviy, and other fields where high refractory performance is required.

High strength and good wear resistance

Green silicon carbide has high strength and wear resistance, which is 5-20 times that of cast iron and rubber. In areas of severe wear (such as blast furnace belly bricks, ladle linings, and wear-resistant pipes), it can withstand material erosion and wear, significantly reducing the frequency of replacement.

Low coefficient of thermal expansion and thermal shock resistance

Green silicon carbide has a low coefficient of thermal expansion and high thermal shock resistance. It is less prone to cracking or spalling when subjected to rapid temperature changes, thus maintaining kiln stability.
