Method for preparing partially stabilized zirconia ceramic by doping calcium oxide
The invention relates to the technical field of microwave ceramic preparation, and relates to a method for preparing partially stabilized zirconia ceramic by doping calcium oxide. High-purity monoclinic-phase zirconium oxide is used as a main raw material, high-purity calcium oxide is used as a doping phase, mixing is performed, and the partially-stabilized zirconium oxide ceramic is obtained under the action of microwave-assisted calcination. The method comprises the following steps: a, fully drying monoclinic phase zirconium oxide and oxidation phase zirconium oxide in a drying oven at 80 DEG C for 11 hours, and carrying out mechanical ball milling according to the proportions of 1: 0.3, 1: 0.5 and 1: 0.7; and b, placing the split samples subjected to mechanical ball milling into a mold, and carrying out mold pressing under the pressure of 100-200KG. And c, putting the zirconium oxide and calcium oxide mixture in the mold into a microwave tube furnace, calcining at 700-1200 DEG C for 1-4 hours, and then cooling to room temperature along with the furnace to obtain a calcium oxide doped partially stabilized zirconium oxide product. By adopting a new method and a new means, production process parameters are adjusted, and the performance of the partially stable zirconium oxide is controlled.
