Application
-Silicon carbide is frequently used in semiconductor and coating
industries.
-SiC tubes are used to serve as components in industrial furnaces
and thermal couple protectors.
-It can be used in high temperature applications.
The reaction-bonded silicon carbide ceramic products, with high
strength, high rigidity, wear resistance, high-temperature
resistance, corrosion resistance, antioxidation, thermal-shock
resistance and good thermal conductivity,
quick-cooling/quick-heating resistance, and high-temperature creep
resistance, are widely applied to military industry, aerospace and
aviation, nuclear power, liquid crystal, metallurgy, chemicals,
machinery, automobile, paper-making, medicine, etc.. Our products
are sold to more than 40 countries and regions, such as USA,
Germany, Japan, Korea, UAE, South Africa, Taiwan, etc.
Technical ceramics due to its exceptional properties is widely used
for the production of refractory products, including lining and
fittings of various shapes for furnace equipment:
- corrosion resistance;
- resistance to heat shock;
- stability of shape and strength preservation at the maximum
operating temperature;
- low weight;
- high reliability and economy in operation.
