Reaction bonded silicon carbide (RBSC) is a type of ceramic material that is formed through a chemical reaction between silicon and carbon.
It is known for its exceptional mechanical and thermal properties, making it suitable for various high-temperature and abrasive applications.
Here are some key characteristics:
1. **Production Process**: RBSC is produced by infiltrating porous carbon preforms with liquid silicon.
The silicon infiltrates the carbon matrix and reacts with it to form silicon carbide,creating a dense and strong composite material.
2. **High Temperature Resistance**: RBSC can withstand extremely high temperatures, making it ideal for applications in environments with severe thermal conditions.
It retains its mechanical strength at temperatures well above 1000°C.
3. **Excellent Hardness**: It is known for its exceptional hardness and wear resistance, which makes it suitable for applications in abrasive environments,
such as cutting tools and wear-resistant components.
4. **Chemical Inertness**: RBSC is chemically inert and does not easily react with most chemicals, which adds to its suitability in harsh industrial environments.5. **Structural Integrity**: It has good structural integrity and is resistant to thermal shock, making it useful in applications where rapid temperature changes occur.
Common applications of reaction bonded silicon carbide include kiln furniture, burner nozzles, pump components, and various parts for high-temperature
and abrasive environments such as mechanical seal faces.
