Silicon nitride ceramic precursor containing sintering aid, preparation method of silicon nitride ceramic precursor and silicon nitride ceramic containing sintering aid
The invention belongs to the technical field of ceramic materials, and relates to a silicon nitride ceramic precursor containing a sintering aid, a preparation method of the silicon nitride ceramic precursor and silicon nitride ceramic containing the sintering aid. The preparation method of the silicon nitride ceramic precursor containing the sintering aid comprises the following steps: adding a metal simple substance and/or a metal salt and a halogenosilane monomer into a solvent, dissolving, adding ammonia or amine, and reacting; and carrying out reduced pressure distillation and purification, and carrying out cross-linking and curing to obtain the silicon nitride ceramic precursor containing the sintering aid. According to the method, the target sintering aid can be generated in situ in a customized mode according to needs, the mixing uniformity of the sintering aid and the silicon nitride ceramic is improved, the problem that the oxygen content is increased due to the fact that the sintering aid is additionally added is greatly solved, a high-purity and high-quality silicon nitride ceramic raw material containing the sintering aid is provided for related industries, and the method has high application value.
本发明属于陶瓷材料技术领域，涉及一种含烧结助剂的氮化硅陶瓷先驱体及其制备方法和含烧结助剂的氮化硅陶瓷。所述含烧结助剂的氮化硅陶瓷先驱体的制备方法，包括以下步骤：将金属单质和/或金属盐、卤硅烷单体加入溶剂中，溶解后，加入氨或胺，进行反应；经减压蒸馏提纯，再经交联固化得到含烧结助剂的氮化硅陶瓷先驱体。该方法可根据需要定制化原位生成目标烧结助剂，提高烧结助剂与氮化硅陶瓷的混合均匀度，大大降低了额外添加烧结助剂引发的氧含量提高的问题，为相关产业提供高纯度、高质量的含烧结助剂氮化硅陶瓷原料，具有较高的应用价值。
