ZrO2 Ceramic Tubes and Rods have the advantages of super hardness, high wear-resisting, good corrosion resistance, high-temperature tolerance, high strength, high mechanical strength, good chemical stability, polishing surface, and so on.
Zirconia Rod and Zirconia Tube are made of ZrO2 ceramics. Zirconia is an extremely refractory material. It possesses excellent chemical inertness and corrosion resistance at temperatures up to 2200ºC, well above the melting point of alumina. Zirconia is stabilized in the cubic crystal structure to avoid cracking and mechanical weakening during heating and cooling.
