Controllable preparation method of calcium oxide-doped toughened zirconium oxide
The invention discloses a controllable preparation method of calcium oxide-doped toughened zirconium oxide. A technical prototype for controllable preparation of partially-stabilized zirconium oxide by microwave heating is constructed. The influence of the phase change of the calcium oxide partially stabilized zirconia is researched by analyzing and characterizing an experimental sample and controlling experimental conditions of calcining temperature and heat preservation time. The experimental result of preparing the calcium oxide partially stabilized zirconia through microwave heating shows that the martensite phase transformation temperature of the zirconia in the heating stage under the microwave action is reduced to some extent. Meanwhile, the microwave heat treatment for preparing the calcium oxide partially stabilized zirconia is short in reaction time, high in heating rate, easy to form a microstructure with small particle size and uniform distribution, free of by-products and more beneficial to environmental protection. Therefore, the method disclosed by the invention has good and wide applicability and has good modification capability on samples, and the prepared zirconium oxide sample meets the requirements of modern ceramic application.
本发明公开了一种掺杂氧化钙增韧氧化锆的可控制备方法，构建部分稳定氧化锆微波加热可控制备的技术原型。通过对实验样品的分析表征，以及控制煅烧温度和保温时间的实验条件来研究氧化钙部分稳定氧化锆相变的影响。微波加热制备氧化钙部分稳定氧化锆的实验结果表明，微波作用下氧化锆在升温阶段的马氏体相变温度有所降低。同时，微波热处理制备氧化钙部分稳定氧化锆反应时间短、升温速率快，易于形成颗粒尺寸小，且分布均匀的微观结构，无副产物产生，更有利于绿色环保。由此表明，本发明具有良好而广泛的适用性，对于样品均具有良好的改性能力，所制备的氧化锆样品符合现代陶瓷应用的要求。
