Preparation method of aluminium oxide-silicon oxide-zirconium oxide ternary compound aerogel
The invention relates to a preparation method of heat-insulating aluminium oxide-silicon oxide-zirconium oxide ternary compound aerogel. The preparation method comprises the following steps: using inorganic aluminium salt, silicon salt, inorganic zirconium salt as precursors, an alcohol solvent and water as reaction solvents, and epoxide as a gel accelerator, performing supercritical fluid drying process to obtain the block-shaped ternary compound aerogel with excellent performance. The obtained ternary compound aerogel sample is low in density, good in elasticity and stable in performance; compared with single aluminium oxide aerogel, single silicon oxide aerogel and single zirconium oxide aerogel, the ternary compound aerogel can bear higher temperature and is more stable in quality; through excellent high temperature stability, the application range of the ternary compound aerogel is extended, so that the ternary compound aerogel can be used in the field of heat insulation.
