摘要

三氧化二铝(Al2O3)气凝胶广泛用于高温、隔热和催化领域,但随温度的上升,Al2O3气凝胶会有一系列的相转变,导致孔洞结构大幅度坍塌,限制其使用范围。综述了Al2O3气凝胶的高温性能和力学性能的改性方法,展望了Al2O3气凝胶未来的发展。

Abstract

Al2O3 aerogel can be used in heat insulation and catalyst.With the increase of the temperature,a series of phase transitions will occur of Al2O3 aerogel,which leads to massive collapse of the pore structure and limits the use range.The modification methods of high temperature performance and mechanical performance of Al2O3 aerogel were reviewed.The development of Al2O3 aerogel was also prospected.
