Zusammenfassung:The invention discloses yttrium-silicon reinforced zirconium aerogel and a preparation method thereof. The preparation method of the yttrium-silicon reinforced zirconium aerogel comprises the following steps: preparing silica sol and zirconium-yttrium composite sol; preparing yttrium-silicon composite zirconium gel based on the silica sol and the zirconium-yttrium composite sol; aging the yttrium-silicon composite zirconium gel in an aging solvent, wherein the aging temperature is 25-60 DEG C; the aging solvent comprises one or more of ethanol, tetraethoxysilane and heptane; the volume ratio of the aging solvent to the yttrium-silicon composite zirconium gel is (1-2): 1; the aged yttrium-silicon composite zirconium gel is subjected to supercritical drying through a drying medium, and the yttrium-silicon reinforced zirconium aerogel is obtained; the drying medium comprises ethanol or carbon dioxide, and the supercritical drying temperature is 260-280 DEG C; the prepared yttrium-silicon reinforced zirconium aer
