Product Specification
| High Light | Thermally Stable Square Beams ，High Temperature Kilns Square Beams ，Load Bearing Square Beams | ||
Recrystallized Silicon Carbide Square Beams (RSiC Beams) are high-performance structural ceramic components designed for load-bearing applications in industrial kilns and high-temperature furnaces.
Manufactured from high-purity silicon carbide through advanced slip casting and recrystallization sintering above 2500°C, RSiC square beams provide outstanding thermal shock resistance, dimensional stability, oxidation resistance, and long-term reliability at temperatures up to 1650°C.
Their lightweight yet robust structure makes them an ideal solution for kiln furniture systems requiring stable support under repeated thermal cycling.
With high thermal conductivity and low thermal expansion, RSiC beams withstand rapid heating and cooling cycles without cracking.
Ideal for:
Unlike many refractory materials, RSiC maintains stable mechanical performance at elevated temperatures.
This allows the beam to support heavy kiln loads while maintaining structural integrity throughout the firing cycle.
Bulk Density:
2.65–2.75 g/cm³
The lightweight design helps:
RSiC forms a protective silica layer during operation, providing excellent oxidation resistance and stable performance in oxidizing atmospheres up to 1650°C.
