Description	We studied sonochemical synthesis of yttrium, lanthanide and uranium oxides and phosphates from solutions of particular metal precursors, such as metal nitrates, acetates, and acetylacetonates, in organic solvents. Nonaqueous solvents, such as tetraglyme (tetraethyleneglycol dimethylether, TGL) and trialkylphosphates, OP(OR)3, R = Me (TMP), Et (TEP), nBu (TBP), were employed. Phosphates served both as solvents and reactants. Sonolysis provided amorphous precipitates that were converted to particular metal oxides and phosphates by calcination. All obtained precipitates were characterized by ICP/OES, by nitrogen adsorption isotherms, by DLS, IR spectroscopy, SEM, TG/DSC analysis and powder XRD analysis. Sonolysis of a series of uranyl nitrate, acetate, and acetylacetonato complexes, M(acac)3, M = Y, La, Ce, Pr, Nd, Eu, Dy, Er, and UO2(acac)2 was carried out in TGL, TMP, TEP, and TBP under Ar on a Sonics and Materials VXC 500 W and working frequency of 20 kHz.
