NBSiC is well-known for its excellent wear resistance and oxidation resistance, high thermal conductivity, and thermal shock resistance, even at high temperatures.
Compared to conventional kiln furniture, they are much stronger and highly resistant to warping, leading to a much longer working life than other kiln shelves.
1. Excellent distortion resistance at high temperatures.
2. High thermal conductivity
3. Low thermal expansion coefficient
4. High hardness
5. Excellent wear resistant
6. Good chemical resistance against acid, molten salts, and halogens
NBSiC supports are widely used as refractory structure parts in the kiln and furnace to produce alumina ceramic, electric ceramics, high voltage ceramics, sanitary ware, daily porcelain ware, and foamed ceramics industry etc.
