Preparation method of C/ZrO2 composite coating modified fiber mullite precursor
The invention discloses a preparation method of a C/ZrO2 composite coating modified fiber mullite precursor in the field of mullite ceramics, which comprises the following steps: by taking 2-hydroxyterephthalic acid as a carbon source and zirconium tetrachloride as a zirconium source, carrying out reaction on the fiber mullite precursor to form carbon/zirconium element doping with a special distribution structure, and carrying out high-temperature pyrolytic reaction to obtain the C/ZrO2 composite coating modified fiber mullite precursor. A C/ZrO2 composite coating is formed and can be attached to the surface of the fiber mullite ceramic, so that the mechanical property of the fiber mullite is improved.
本发明公开了莫来石陶瓷领域的一种C/ZrO2复合涂层改性纤维莫来石先驱体的制备方法，以2‑羟基对苯二甲酸为碳源，以四氯化锆为锆源，通过在纤维莫来石前体物上进行反应，形成具有特殊分布结构的碳/锆元素掺杂，经过高温热解反应后，形成C/ZrO2复合涂层，能够附着于纤维莫来石陶瓷表面，改善纤维莫来石的力学性能。
