Reaction-Bonded Silicon Carbide (RB-SiC): The Benchmark for High-Performance Ceramics
In demanding thermal and corrosive environments, material performance is non-negotiable. Our Reaction-Bonded Silicon Carbide (RB-SiC) products are engineered to deliver unmatched reliability and efficiency. By combining exceptional mechanical strength, outstanding thermal properties, and superior chemical resistance, RB-SiC sets the standard for components in high-temperature heat transfer, wear-resistant linings, and precision engineering applications.
Engineered for Extreme Conditions
RB-SiC is a composite ceramic material fabricated through a unique reaction-sintering process. This method results in a fully dense, pore-free microstructure that provides:
- Exceptional Thermal Stability & Conductivity: Maintains integrity and efficiently transfers heat at extreme temperatures.
- Superior Mechanical Strength & Hardness: Offers excellent resistance to wear, abrasion, and mechanical shock.
- Outstanding Chemical Inertness: Withstands corrosive attack from acids, alkalis, and molten metals.

Key Performance Highlights
Strength That Increases with Heat: Unique among engineering materials, our RB-SiC's flexural strength actually increases from 250 MPa at room temperature to 281 MPa at 1200 °C, ensuring reliability when it matters most.
Near-Zero Porosity: With ≤ 0.1% porosity, the material is impermeable to gases and liquids, enhancing its corrosion resistance and mechanical integrity.
Optimal Thermal Management: The combination of high thermal conductivity (45 W/m*K at 1200°C) and a low thermal expansion coefficient (4.5 ×10⁻⁶/K) ensures minimal thermal stress, excellent thermal shock resistance, and efficient heat transfer.
