Bongsa silicon carbide heating elements which uses high-purity green silicon carbide as main materials and be recrystallized to be formed above 2300º C.

Because of its stable chemical property, high mechanical strength, small coefficient of heat expansion, convenient installation and maintenance, it can be used in an air atmosphere up to 1500º C without any protection atmosphere under rational condition, it can be continuously used over 5000 hours. It is suitable for electric kiln and furnace and has been widely used in the fields of national defense, mechanism, metallurgy, light chemical industry, ceramics, electron, glass, analysis test and scientic research, it plays an important role in national economy.
