Kam tai High temperature refractory Silicon carbide kiln shelves
1. Details
Refractory silicon carbide kiln shelves is distinguished by high
strength that stays nearly constant up to very high temperatures
(1500° C), maintaining that strength over long periods.
This material displays an extremely high corrosion resistance in
acidic and basic media, and this too is maintained up to very high
temperatures. These properties are outstanding among
high-temperature ceramics, and are complemented by high thermal
shock resistance, high thermal conductivity, high resistance to
wear, and hardness close to that of diamond.
It is Widely used in various heat treatment furnace, glass
annealing furnace, ceramic sintering furnace, diffusion furnace and
ceramic industry, shelf panels, pillars, chemical industry, a
variety of sagger, kiln liner, the environmental protection
industry incinerator liner. Dimensions products, physical and
chemical indicators, life had been reached or exceeded the level of
similar products at home and abroad.

4. Application
Silicon carbide kiln shelves applied to Sanitary ceramics
Our Silicon carbide kiln shelves can offer high mechanical strength
at high temperature, excellent heat stability, good distortion
resistance at high temperature and oxidization resistance. It can
be used in high class washing basin, high-class bowl and bowl
urinal. Through the burning of 1300° C, it provides high enamel and
high abrasion resistance. It can keep gloss and quality for 10
years. Our brand enjoy good reputation in this trade. We are
improving our product and introducing green into our sales
activity.
