Method for preparing SiBCN ceramic precursor by recycling by-product, product and application of SiBCN ceramic precursor
The invention discloses a preparation method of a SiBCN ceramic precursor as well as a product and application thereof, and the preparation method comprises the following steps: by taking chlorosilane, boron trichloride, optionally added or not added disilazane and a SiBCN ceramic precursor by-product as raw materials, carrying out heating reaction under the protection of inert atmosphere by adopting a one-pot method to prepare the SiBCN ceramic precursor, namely PBSZ. According to the method, the PBSZ byproduct is recycled and used as a raw material to prepare the precursor, so that the problem that the byproduct generated in the process of preparing the PBSZ by a one-pot method cannot be treated is fundamentally solved, the environmental pollution is reduced, the production cost is effectively reduced, and the raw material can be recycled.
本发明公开了一种SiBCN陶瓷前驱体的制备方法及其产物和应用，所述制备方法包括：以氯硅烷、三氯化硼、任选加入或者不加入的二硅氮烷、和SiBCN陶瓷前驱体副产物为原料，采用一锅法，在惰性气氛保护下，加热反应，制备SiBCN陶瓷前驱体、即PBSZ。本发明将PBSZ副产物循环再利用、作为原料制备所述前驱体，从根本上解决了“一锅法”制备PBSZ过程中产生的副产物无法处理的问题，减少环境污染，有效降低生产成本，实现原料的可循环利用。
