Thermally Stable Recrystallized Silicon Carbide Ceramic Square Beams Designed for Load Bearing and Long Term in High Temperature Kilns

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:

• Tunnel kilns
• Roller kilns
• Shuttle kilns
• Fast-firing systems

Unlike many refractory materials, RSiC maintains stable mechanical performance at elevated temperatures.

• Flexural Strength @ 20°C: 90–100 MPa
• Flexural Strength @ 1200°C: 100–110 MPa
• Compressive Strength: 300 MPa

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:

• Reduce kiln car weight
• Lower energy consumption
• Minimize support loading
• Improve operational efficiency

RSiC forms a protective silica layer during operation, providing excellent oxidation resistance and stable performance in oxidizing atmospheres up to 1650°C.

Benefits include:

• Reduced maintenance frequency
• Lower replacement costs
• Improved kiln uptime

Custom dimensions are available upon request.

RSiC Square Beams are widely used in:

• Alumina ceramics
• Zirconia ceramics
• Honeycomb ceramics
• Technical ceramics

• Cathode material production
• Anode material processing
• Continuous roller kiln systems

• Kiln support structures
• High-temperature firing systems
