Silicon Nitride Bonded Silicon Carbide (NSiC) Fish-Shaped Kiln Shelves
Silicon Nitride Bonded Silicon Carbide (NSiC) Fish-Shaped Kiln Shelves
Product Overview
Our NSiC fish-shaped kiln shelves are multifunctional structural supports designed for high-load kiln furniture systems. With a unique fish-like profile, they serve both as load-bearing shelves and as connecting frames that integrate seamlessly with beams, rollers, and other kiln components. The silicon nitride-bonded SiC matrix ensures superior thermal stability, mechanical strength, and oxidation resistance under extreme firing conditions.
