Detailed Product Description：
Ceramic Rod(Ceramic stick) Aterial quality: Cream-coloured characteristic of alumina 95 chinas 99 chinas white: The thermostability, the intensity are high, able to endure mean, be able to bear corrosion, does not explode to crack, water absorption use may not come to pursue making to order.
Ceramic rod products are available in a variety of shapes and types. Recuperator tubes are cross-shaped ceramic components that recover heat from combusted gases. Degassers are sometimes porous and bar stock usually has a square cross-section. Immersion tubes protect heating elements, burners, and other devices in high temperature furnaces from immersion in molten metal, glass, or other melted materials. Muffle or furnace tubes form a barrier between the heating elements and heated parts in a furnace.
