Alumina ceramic and preparation method thereof
The invention belongs to the technical field of aluminum oxide ceramics, and particularly relates to an aluminum oxide ceramic and a preparation method thereof. The invention provides an aluminum oxide ceramic. The aluminum oxide ceramic is prepared from the following raw materials in parts by mass: 90-110 parts of aluminum oxide, 1-5 parts of a rare earth material and 5-10 parts of fibers. According to the invention, by introducing rare earth elements, the grain boundary and microstructure can be optimized, and the rare earth elements and a mechanical support network formed by fibers supplement each other; and the addition of rare earth elements can enhance the binding force between the fiber and the matrix, thereby enhancing the enhancement effect. Through the synergistic effect of the rare earth elements and the fibers, not only are the bending strength and the fracture toughness improved remarkably, but also the wear resistance, the corrosion resistance and the high temperature resistance of the material can be improved, so that the final aluminum oxide ceramic has wider engineering application potential.
本发明属于氧化铝陶瓷技术领域，具体涉及一种氧化铝陶瓷及其制备方法。本发明提供了一种氧化铝陶瓷，制备原料包括以下质量份数的组分：氧化铝90～110份，稀土材料1～5份，纤维5～10份。在本发明中，通过引入稀土元素，能够优化晶界和微观结构，与纤维形成的力学支撑网络相辅相成；同时稀土元素的添加能够增强纤维与基体的结合力，从而提升其增强效果。本发明通过稀土元素和纤维的协同作用，不仅在提高抗弯强度和断裂韧性上有显著效果，还能改善材料的耐磨性、耐腐蚀性和耐高温性能，使得最终的氧化铝陶瓷具备更广泛的工程应用潜力。
