Aluminum lactate - An attractive precursor for sol-gel synthesis of alumina-based glasses
Abstract
A novel aluminum precursor, aluminum lactate (Al(lact)3), was used in the sol-gel synthesis of alumina-based systems. The peculiar chelation properties of aluminum lactate in aqueous solution make this precursor quite attractive for the sol-gel synthesis of alumina-containing materials. Based on the reaction of aluminum lactate with different precursors such as phosphorus, boron, fluorine and others, (Na2O-)Al2O3-P2O5, (Na2O-)Al2O3-B2O3, (Na2O-)Al2O3-B2O3-P2O5, (Na-)Al-P-O-F, amorphous gels and glasses were prepared. The local structures of glasses prepared by both sol-gel and melt-cooling methods were compared by using solid state NMR.
