- Abstract
SiO2-Al2O3 composite aerogel (SAA) has shown a wide range of application in aerospace, chemical metallurgy, furnace insulation and other fields due to the characteristics of low bulk density, high specific surface area, low thermal conductivity and high temperature resistance. Ambient pressure drying has the advantages of low preparation cost, easy industrial mass production and so on, so it has a good practical application prospect. In this work, the preparation methods of SAA were introduced, with emphasis on the research status of precursors, surface modifiers and fiber reinforcements in the preparation of SAA by ambient pressure drying. Finally, the development direction of SAA prepared by ambient pressure drying was prospected.
