Preparation method of zirconium diboride ceramic precursor
The invention relates to the technical field of material chemistry, and in particular relates to a preparation method of a zirconium diboride ceramic precursor. The preparation method of the zirconium diboride ceramic precursor comprises the following steps: 1 preparing raw materials; 2 synthesizing a zirconium-containing polymer PZS; and 3 preparing a ZrB2 ceramic precursor. Zirconium oxychloride, acetylacetone and ortho-hydroxybenzyl alcohol are subjected to condensation polymerization in an alkaline condition to prepare the zirconium-containing polymer, and the polymer is mixed with boric acid in a solution to obtain the ZrB2 ceramic precursor. The ceramic precursor prepared by the method can form a homogeneous steeping liquor, has relatively high ceramic conversion rate, meets the requirements of a PIP technology, and has a wide application prospect in construction of a ZrB2 ceramic-modified C/C composite material.
