Reputation depends on quality, quality comes from Hard!
Zirconia Ceramic:
The zirconium oxychloride (ZrCl2O.8H2O) is recrystallized from hydrochloric acid or methanol and calcined at a high temperature to obtain a finished product. The tetraalkoxy zirconium is distilled and purified, and the vapor is decomposed at 350 to 500 ° C to obtain a finished product.
The zirconium tetrachloride is distilled and purified, and the vapor is reacted with excess oxygen at 1200 ° C to obtain zirconium dioxide.
Preparation process
Stabilized zirconia for industrial refractories, mostly made by electrofusion. In the process of zircon electrofusion, carbon and stabilizer calcium oxide are added. At the same time as silicon removal, zirconia and calcium oxide react to form a solid solution, and then pulverized and granulated to obtain stable zirconia. Stable and partially stabilized zirconia for fine ceramics is typically prepared by wet processing.
