Preparation method of SiBCN ceramic precursor containing borazine structure
A preparation method of a SiBCN ceramic precursor containing a borazine structure belongs to the field of inorganic non-metal materials. The preparation method comprises the following steps of: firstly, preparing methylchlorosilane into a Grignard reagent, and taking the Grignard reagent to react with chlorine-containing borazine to obtain a micro-molecular structure containing the borazine structure; and furthermore, carrying out aminolysis on a micro-molecular product containing a Si-CI group to obtain a corresponding polymer product. A micro-molecule and a polymer are SiBCN ceramic precursors. The problems of an existing preparation method that a process is difficult to control, the product is difficult to prepare in batches and the like are solved. According to the preparation method provided by the invention, the cost of raw materials is low, the product with higher purity is easy to obtain and the product can be prepared in batches.
