摘要

A novel monolithic yttria-alumina aerogel was successfully prepared using inorganic precursors through the sol-gel method. The yttria-alumina aerogel possesses a three-dimensional network structure composed of numerous nanoscale flake like particles and nanoscale pores. In addition, the aerogel is mainly made up of nano Y₂O₃ grains, and Al atoms are dissolved in the Y₂O₃ grains to form the solid solution. The aerogel with a low density of 0.203 g/cm³ exhibits low thermal conductivity of 0.016 W/(m·K). Therefore, the yttria-alumina aerogel shows promise for application as a thermal insulation material.
