Zirconium oxide toughened aluminum oxide composite ceramic material and preparation method thereof
The invention provides a zirconium oxide toughened aluminum oxide composite ceramic material. The zirconium oxide toughened aluminum oxide composite ceramic material comprises the following raw materials in parts by mass: 5-10 parts of zirconium oxide powder, 75-90 parts of aluminum oxide powder and 2-10 parts of a sintering aid; the sintering aid comprises lanthanum oxide and magnesium oxide. The invention also provides a method for preparing the composite ceramic material. The method comprises the following steps: preparing a precursor mixed solution of lanthanum oxide and magnesium oxide; preparing zirconium oxide powder and aluminum oxide mixed powder; molding the mixed powder to prepare a green body; sintering the green body for the first time to obtain the ceramic green body; dipping a ceramic green body in the precursor mixed solution for a period of time, and sintering for the second time. According to the preparation method of the zirconium oxide toughened aluminum oxide multiphase ceramic material, the effect of the sintering aid can be fully played, the sintering temperature is effectively reduced, energy is saved, and the comprehensive performance of the zirconium oxide toughened aluminum oxide multiphase ceramic material prepared by the method is excellent.
