The advantages of black silicon carbide refractory material

Black silicon carbide is an excellent refractory material. It is widely used as a furnace lining, kiln furniture, firebrick, and crucibles.

It has several advantages in the refractory industries:

1. High-Temperature Resistance: Black silicon carbide can withstand extremely high temperatures. The maximum resistance temperature is up to 1850-1900 degrees. That makes it ideal for applications where the material is exposed to intense heat.

2. Hardness and Abrasion Resistance: It is a very hard material, ranking close to diamond on the Mohs scale. (Diamond 10.0, black silicon carbide 9.2)This hardness provides excellent resistance to wear and erosion, making it well-suited for abrasive environments.

3. Chemical Inertness: Black silicon carbide is chemically inert and resists chemical attack from most acids and alkalis. Even at 1400 degree temperature, it is still suitable for use in corrosive environments.

4. Thermal Conductivity: It has relatively high thermal conductivity, which allows for efficient heat transfer and distribution.

5. Low Thermal Expansion: Black silicon carbide exhibits low thermal expansion, minimizing the risk of thermal stress and cracking at high temperatures.

6. Stability and Durability: Black silicon carbide is stable and durable, with good resistance to thermal shock and thermal cycling.

Overall, these properties make black silicon carbide an excellent choice as a refractory material in high-temperature and abrasive environments.  Black silicon carbide sand 0-1mm,1-2mm,1-3mm,1-5mm, and 0-10mm are suitable for refractory aggregates and castables.
