Silicon nitride (Si3N4) profile

ceramicsquareconstruction

Product Overview
Our beams and profiles are load-bearing constructional elements for mass-optimized kiln car superstructures, used as kiln furniture for firing ceramics in the Sanitary, Electro-Porcelain and Architectural Ceramics segments. The RBSiC grades CarSIK and Eco-Light® Sanitary (for sanitary applications) exhibit up to ~40% higher bending strength and improved creep resistance versus commonly available competitor products, primarily due to a combination of high bulk density and low free silicon content. The Eco-Light® Sanitary microstructure enables smaller beam cross-sections (≤30x30mm), reducing thermal mass and energy consumption.

High-temperature grade
For elevated temperatures in the range >1,380°C ≤1,470°C we offer the silicon-nitride-bonded CarSIK-NG (NSiC) grade.

You benefit from these advantages

• Available grades: RBSiC (CarSIK-Z, CarSIK-G, Eco-Light®), NSiC (CarSIK-NG)
• Increased bending strength and enhanced creep resistance
• Excellent oxidation and corrosion resistance
• Good thermal shock resistance
• Lower thermal mass (positive impact on energy consumption)
• Product-related services for Eco-Light®: economic-efficiency calculation, technical support, integrated pro‑rated 5-year product warranty (expandable to 10 years on request)
