Preparation method of liquid-phase ZrC high-temperature-resistant ceramic precursor
The invention relates to a preparation method of a liquid-phase ZrC high-temperature-resistant ceramic precursor. The invention relates to a preparation method of a liquid-phase ZrC high-temperature-resistant ceramic precursor, aims to solve the problems of high synthesis temperature and high cost in the existing method for preparing a carbide ceramic material, aims to synthesize a ZrC ceramic precursor, and mainly solves the problem that Zr is crosslinked in ethylenediamine and diallylamine in the reaction process. An XPS test result of the precursor shows that a new chemical bond, namely a Zr-N bond, is formed in the reaction process, N and Zr are connected through a covalent bond, a precursor polymer containing a large amount of N, Zr, Cl and C elements is formed, and the ZrC ceramic precursor is obtained. Organic and inorganic conversion can be realized in a low-temperature environment, a sintering aid does not need to be added, and the cost is low. The method is suitable for the field of ceramic precursor preparation.
一种液相ZrC耐高温陶瓷先驱体的制备方法。本发明涉及一种液相ZrC耐高温陶瓷先驱体的制备方法，本发明的目的是为了解决现有制备碳化物陶瓷材料的方法中合成温度较高、成本高的问题，本发明以合成ZrC陶瓷先驱体为目的，重点解决在反应过程中将Zr元素交联在乙二胺、二烯丙基胺中。由先驱体的XPS测试结果可知在反应过程中形成了新的化学键，即Zr‑N键，通过共价键将N、Zr连接起来，形成含有大量N、Zr、Cl、C元素的先驱体聚合物，得到一种ZrC陶瓷先驱体的制备方法。本发明在较低的温度环境中便可实现有机、无机转换，无需添加烧结助剂，成本低。本发明适用于陶瓷先驱体制备领域。
