The invention relates to ZrO2-Al2O3 ceramic fiber aerogel and a preparation method of the ZrO2-Al2O3 ceramic fiber aerogel. According to the ZrO2-Al2O3 ceramic fiber aerogel and the preparation method thereof provided by the invention, the ZrO2-Al2O3 ceramic fiber aerogel product is prepared through the key steps of ZrO2-Al2O3 ceramic fiber film preparation, stacking, dipping, freeze drying, sintering and the like. In the ZrO2-Al2O3 ceramic fiber aerogel prepared by the invention, each layer of ZrO2-Al2O3 ceramic fiber film is composed of wavy nano ceramic fibers with pores, the thickness of each layer of ZrO2-Al2O3 ceramic fiber film is about 150 microns, the nano ceramic fibers are horizontally and randomly distributed in the ZrO2-Al2O3 ceramic fiber film, and the nano ceramic fibers are of a loose layered structure in the vertical direction; the diameter of the ceramic fibers is 380-740 nanometers, the ceramic fibers are flexible and have high deformation resistance, and the number of stacked layers can be determined according to actual needs. The preparation method of the ZrO2-Al2O3 ceramic fiber aerogel provided by the invention is effective and controllable in process, and the ZrO2-Al2O3 ceramic fiber aerogel finished product can be prepared into any shape and thickness.
本发明涉及一种ZrO2‑Al2O3陶瓷纤维气凝胶及其制备方法。采用本发明所提供的ZrO2‑Al2O3陶瓷纤维气凝胶及其制备方法，通过ZrO2‑Al2O3陶瓷纤维薄膜制备、堆叠、浸渍、冷冻干燥、烧结等关键步骤制得ZrO2‑Al2O3陶瓷纤维气凝胶产品。本发明制备得到的ZrO2‑Al2O3陶瓷纤维气凝胶中，每层ZrO2‑Al2O3陶瓷纤维薄膜由波浪形、带气孔的纳米陶瓷纤维构成，每层ZrO2‑Al2O3陶瓷纤维薄膜厚约150微米，纳米陶瓷纤维在ZrO2‑Al2O3陶瓷纤维薄膜中水平随机分布，竖直方向为松散的层状结构；陶瓷纤维直径380～740纳米，表现为柔性，且有很强的抗变形能力，可根据实际需要决定堆叠的层数。本发明提供的ZrO2‑Al2O3陶瓷纤维气凝胶制备方法过程有效、可控，并可将ZrO2‑Al2O3陶瓷纤维气凝胶成品制成任意形状和厚度。
