Abstract

This paper reviews the preparation processes, high-temperature resistance, and the latest research progress on high-temperature infrared modification of Al₂O₃-SiO₂ aerogel thermal insulation materials. Researchers, based on the high-temperature phase transition behavior of Al₂O₃-SiO₂ aerogels, have proposed strategies to enhance temperature resistance by increasing the crystallinity of the nanoscale skeleton and introducing elemental doping, and further carried out IR-opacified modification to improve the suppression of infrared radiative heat transfer at high temperature. Moreover, from the perspective of practical applications, this paper also presents prospects for future research directions of Al₂O₃-SiO₂ aerogel thermal insulation materials.
