Product Description
Premium-Grade Sintered Silicon Carbide (SSiC) Structural Beams
Engineered for extreme‑temperature and high‑load environments, these anti‑creep structural beams are manufactured by extrusion and pressureless sintering at 2100-2200 °C. The resulting SSiC components offer unmatched mechanical strength, near‑zero thermal expansion, and exceptional resistance to creep under sustained thermal and mechanical stress.
Key Features & Engineering Advantages
- High‑Temperature Structural Integrity
Retains flexural strength of 300-400 MPa at temperatures up to 1650 °C. - Ultra‑Low Thermal Expansion
Coefficient of thermal expansion (CTE) of 4.0 × 10⁻⁶/K ensures dimensional stability under repeated thermal cycling. - Superior Long‑Term Creep Resistance
Maintains shape and load‑bearing capacity under continuous static loads at high temperature, guaranteeing kiln framework stability. - Exceptional Thermal Shock Resistance
Withstands rapid temperature differentials exceeding 350 °C, supported by high thermal conductivity (196 W/(m*K) at 20 °C). - Corrosion & Oxidation Resistance
Resistant to strong acids and alkalis; forms a self‑healing SiO₂ surface layer in oxidizing atmospheres at elevated temperatures.
