Multi-element single-phase boride ceramic powder material as well as preparation method and application thereof
The invention discloses a preparation method and application of a multi-element single-phase boride ultra-high-temperature ceramic precursor and powder, and belongs to the field of ultra-high-temperature ceramic preparation. According to the method, stable and uniform distribution of raw materials is realized by utilizing a liquid phase method, and atomic-level mixing is realized. Through purification steps of multiple times of rotary evaporation, filtration, vacuum drying and the like, impurities are effectively removed, the purity of the product is controlled, and meanwhile, the particle size of the prepared ceramic powder is nanoscale. A polycondensation reaction in the solution directly generates a ceramic polymer precursor with uniform chemical components, and the yield of the precursor is relatively high; because the raw materials are uniformly mixed and the chemical reaction is fully carried out, the finally prepared ceramic powder has the characteristic of uniform element distribution. The method is simple in preparation process, the obtained product is high in purity, small in particle size and uniform in element distribution, and the obtained multi-element single-phase boride ultra-high-temperature ceramic powder can still keep stable chemical properties and physical properties at high temperature and is suitable for being applied to extreme environments such as high temperature and high pressure.
本发明公开一种多元单相硼化物超高温陶瓷前驱体及粉体的制备方法和应用，属于超高温陶瓷制备领域。本方法利用液相法实现原料的稳定均匀分布，实现原子级别的混合。通过多次旋蒸、过滤和真空干燥等纯化步骤，有效去除杂质，控制了产物的纯度，同时，制得的陶瓷粉体粒径为纳米级。溶液中的缩聚反应直接生成了化学成分均一的陶瓷聚合物前驱体，前驱体的产率较高；由于原料的均匀混合和化学反应的充分进行，最终制得的陶瓷粉体具有元素分布均匀的特点。该方法制备工艺简单、得到的产物纯度高、粒径小、元素分布均匀，得到的多元单相硼化物超高温陶瓷粉体在高温下仍能保持稳定的化学性质和物理性能，适用于高温、高压等极端环境下的应用。
