High Strength Kiln Shelves
Advanced reaction bonded sic batts offer superior load-bearing, thermal shock resistance, and flatness for high-temperature kiln operations.
RBSiC/SiSiC silicon carbide batts are high-performance kiln shelves known for excellent strength, flatness, and resistance to thermal shock in high-temperature firing processes.
Silicon carbide batts made from reaction bonded silicon carbide (RBSiC / SiSiC) are essential refractory components used as kiln shelves, plates, or setters in ceramic firing, powder metallurgy, magnetic materials, and sintering applications. These batts are prized for their high strength, excellent flatness, and superior resistance to thermal deformation.
RBSiC (also called SiSiC) has a fine-grained structure, high density, and low porosity, making it ideal for repeated use under extreme temperatures and heavy loading conditions. Unlike conventional alumina or cordierite shelves, SiC batts resist warping, bending, and thermal cracking, even during long firing cycles.
Sunny Steel provides custom-cut SiC batts to fit your kiln dimensions, including drilled holes, slotted edges, and multi-layer stacking supports. Each batt is engineered for long-term thermal cycling, helping clients reduce breakage, increase energy efficiency, and improve firing consistency.

Silicon carbide products are an advanced material widely used in high temperature, high pressure and high frequency environments.:
Composite structure with ordinary steel outer wall meets strength requirements for various industrial processes.
Inner ceramic layer (≥95% content) provides 30x better wear resistance than carbon steel pipes.
Corrosion-resistant composite layer enables use in acid, alkali, and salt environments.
Organic polymer matrix with inorganic ceramic reinforcement provides 14-16 MPa peeling strength (100x stronger than ordinary lining).
Continuous operation from 40°C to 200°C, with peak resistance up to 260°C.
Elbows show no significant wear after 1-2 years, outperforming thick-walled cast steel by nearly 10x.
Silicon carbide ceramic-lined pipes offer superior performance compared to traditional materials:
Our silicon carbide tubes and fittings are carefully packaged to minimize damage during storage and transit, ensuring the original quality remains intact.
We implement anti-vibration and impact-resistant measures to ensure each product arrives safely. Packaging methods are adapted for maritime transport, with corrosion-resistant wrapping and clear identification labels.
