High Temperature Resistance and Heat Insulation of Oxide Aerogels
Oxide aerogel is one type of three-dimensional nano porous material,which has the advantages of high porosity,high specific surface area,low thermal conductivity,high melting point and so on.Moreover,oxide aerogel always shows excellent high-temperature resistance and thermal insulation performance.Thus,in this paper,the research progress of heat-resistant oxide aerogels including silica,alumina,zirconia aerogels,binary and multi-component and their composite counterparts are reviewed.The preparation method and performance of oxide aerogels are summarized,the existing problems are pointed out,and the application of oxide aerogels in the field of high temperature thermal insulation is prospected.
