Alumina Ceramic Tube
Alumina ceramic tubes calcined with zirconia, silicon oxide, silicon nitride and other powder composite ceramic materials will greatly increase the hardness and strength of ceramic tubes, and compared with traditional ceramic tubes, alumina ceramic tubes have lower water absorption, more advanced technology, low cost, relatively large brittleness.
