High Light	High-Temperature Structural Integrity SSiC Structural Beam ，Ultra-Low Thermal Expansion Silicon Carbide Ceramic Beam ，Superior Long-Term Creep Resistance Sintered Silicon Carbide Structural Beam

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.
