Highly dispersed zirconium oxide-aluminum oxide ceramic powder and preparation method thereof
The invention relates to highly dispersed zirconia-alumina ceramic powder and a preparation method thereof, the ceramic powder takes alumina particles as a skeleton, and yttria-stabilized zirconia particles are uniformly dispersed and attached to the surfaces of the alumina particles. According to the highly dispersed zirconium oxide-aluminum oxide ceramic powder provided by the invention, tetragonal-phase zirconium oxide is uniformly dispersed on the surface of aluminum oxide, agglomeration of zirconium oxide and aluminum oxide powder is effectively avoided due to tight combination of a precursor and hydroxyl, and the highly dispersed zirconium oxide-aluminum oxide ceramic powder has good sintering activity and mechanical properties and is beneficial to improvement of hardness and toughness of a ceramic chopper.
本发明涉及一种高度分散的氧化锆‑氧化铝陶瓷粉体及其制备方法，所述陶瓷粉体以氧化铝颗粒为骨架，氧化钇稳定氧化锆颗粒均匀分散附着于氧化铝颗粒表面。本发明提供的高度分散的氧化锆‑氧化铝陶瓷粉体中四方相的氧化锆均匀分散在氧化铝表面，由于前驱体与羟基紧密结合，有效避免了氧化锆和氧化铝粉体的团聚，具有良好的烧结活性和力学性能，有助于提高陶瓷劈刀的硬度和韧性。
