    Nonhydrolytic Sol-Gel Reactions for the Synthesis of Oxide Materials

  • Original language description

    Nonhydrolytic sol-gel processes are promising new routes for the preparation of new oxide, silicate and phosphate materials. These reactions are based on aprotic polycondensations with the elimination of small organic molecules (ethers, esters, alkylhalides, etc.) in the absence of hydroxyl groups. One of our goals was the synthesis of new precursors - aluminum chloride-alkoxides - and their nonhydrolytic transformation to alumina by alkylhalide elimination. The second area of interest was improving thesynthesis of phosphosilicate gels. We prepared phosphosilicate gels by the elimination of acetic acid esters in heteropolycondensation reactions between silicon(IV) acetate and tris(trimethylsilyl) ester of phosphoric acid. The nonhydrolytic ester elimination provides clear amorphous hybrid phosphonosilicate gels at room temperature.
