2. Grade I silicon carbide powder, also known as high-grade refractory black silicon carbide, boasts the same chemical composition as the abrasive version of black silicon carbide. This premium grade is primarily utilized in the production of elite silicon carbide products, such as recrystallized silicon carbide, gas turbine components, nozzles, silicon nitride-bonded silicon carbide pieces, lining for high-temperature zones of blast furnaces, high-temperature kiln components, support parts for high-temperature kilns, fire-resistant saggers, and more. Given its high-quality and superior content, the end products created with it have elevated service values.
The grade II refractory black silicon carbide powder, or grade II silicon carbide, is composed of over 90% silicon carbide and is primarily used in the production of kiln components that require medium to high heat resistance. These components, such as muffle furnace lining materials, benefit from the thermal conductivity and chemical stability that silicon carbide provides. As a result, the use of grade II silicon carbide promotes the advancement of materials and their applications.
The grade III silicon carbide, also known as low-grade refractory black silicon carbide powder, has a silicon carbide content of more than 83%. This type of powder is commonly used for lining iron tapping tanks, hot metal ladles, and in the zinc smelting and sponge iron manufacturing industries. With its superior durability and resistance to high temperatures, grade III silicon carbide is an ideal choice for industrial applications that demand reliable and long-lasting performance. Whether you are working in a steel mill or a foundry, this versatile material can help you achieve greater efficiency and productivity in your operations.
