High-strength electroceramic green body with uniform microstructure and preparation method of high-strength electroceramic green body
The invention discloses a high-strength electroceramic green body with a uniform microstructure and a preparation method thereof, solves the problems of non-uniform microstructure, low strength and high strength dispersity of an existing electroceramic material, and relates to the technical field of ceramics. By controlling the Al2O3 content, the Al2O3 crystal form, the amount of K2O + Na2O + CaO + MgO and the ball-milling particle fineness of the electroceramic material to be smaller than or equal to 5 microns, a high-strength electroceramic green body with a uniform microstructure is prepared, and a three-dimensional interlaced needle-shaped secondary mullite phase and a high-aluminum glass phase enhanced by the three-dimensional interlaced needle-shaped secondary mullite phase are uniformly distributed in the electroceramic green body.
本发明公开了一种微观结构均匀的高强度电瓷坯体及其制备方法，解决了现有电瓷材料微观结构不均匀、强度低、强度分散性大的问题，涉及陶瓷技术领域。本发明通过控制电瓷材料中的Al2O3含量、Al2O3结晶形态、K2O+Na2O+CaO+MgO的量和球磨颗粒细度≤5μm，制得了微观结构均匀的高强度电瓷坯体，其内部三维交织针状二次莫来石相和其增强的高铝玻璃相均匀分布。
