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.
