SiBCN ceramic precursor and preparation method and application thereof
The invention discloses a SiBCN ceramic precursor as well as a preparation method and application thereof, and belongs to the technical field of wave-transparent materials. The preparation method of the SiBCN ceramic precursor comprises the following steps: under the protection of an inert gas atmosphere, taking trichlorosilane, a boron source and hexamethyldisilazane as raw materials, and carrying out condensation polymerization to prepare the SiBCN ceramic precursor. The SiBCN ceramic precursor prepared by the preparation method disclosed by the invention is relatively low in carbon content, and the SiBCN ceramic prepared by adopting the precursor has excellent wave-transparent performance.
本发明公开了一种SiBCN陶瓷前驱体及其制备方法和应用，属于透波材料技术领域。SiBCN陶瓷前驱体的制备方法包括以下步骤：在惰性气体气氛保护下，以三氯硅烷、硼源、六甲基二硅氮烷为原料发生缩聚反应制备得到SiBCN陶瓷前驱体。本发明制备的SiBCN陶瓷前驱体含碳量较低，采用该前驱体制备得到的SiBCN陶瓷具有优异的透波性能。
