ZIRCONIUM OXIDE (ZrO2) BALLS Refractory ceramic material balls, they show excellent corrosion, wear and heat resistance. They improve their hardness if they are subjected to collisions. Yttrium doped Zirconia Oxide, they show the best properties between ceramic materials in grinding and milling applications. Applications Special bearings, pumps and valves that operate in aggressive environments, check valves, flow meters, measurement instruments. They are used in the medical field (very pure material). Grinding and milling applications. Corrosion Resistance Zirconia balls are chemically inert in molten metals, caustic and organic solvents and most acids substances. They do not resist in hydrochloric acid and strong alkaline solutions. More information, please refer to ou website: www.minbearingsteelball.com
