This product is a high-quality silicon nitride-bonded silicon carbide refractory brick designed for extreme high temperatures and harsh working conditions. It is widely used in industries such as metallurgy, aluminum processing, ceramics, and chemicals. It uses a high-quality silicon carbide matrix combined with silicon nitride to achieve excellent mechanical strength, thermal shock resistance (can withstand temperature fluctuations above 1650°C), and long-term service stability. Compared with traditional sintered silicon carbide, it has a lower linear expansion coefficient and better thermal conductivity, significantly extending the life of the kiln and reducing maintenance costs. It has excellent resistance to acid and alkali corrosion and is particularly suitable for environments with contact with molten salts, halogens, or molten metals. We provide customized services for standardized sizes and support export certifications (such as ISO 9001) to ensure that global customers receive consistent and reliable high-performance refractory solutions.
1. High temperature resistance up to 1650°C, strong thermal shock resistance, not easy to crack;
2. The wear resistance is more than 30% better than ordinary silicon carbide bricks;
3. Strong chemical inertness, acid resistance, salt resistance and halogen corrosion resistance;
4. High thermal conductivity, significant energy saving and consumption reduction effect;
5. Customizable dimensions and specifications to suit various kiln structures.
Suitable for high-temperature industrial equipment such as aluminum electrolytic cell sidewalls, blast furnace linings, glass kiln domes, ceramic roller kilns, and waste incinerators. Our products are primarily targeted at manufacturers and engineering contractors in the metallurgical, building materials, and new energy battery material manufacturing industries in Europe, America, Southeast Asia, the Middle East, and Africa.
