The stability constants of the Ag(I) complexes of nine amino-alcohols have been determined at 25.0±0.1 ° and in an ionic medium of 0.5 M KNO3. Because of the high values of k2/k1 the formation curves are very steep and it was preferable to calculat

Starting from a novel water-based Zr(IV)-peroxo-citrato solution, an entirely aqueous solution-gel synthesis of Pb(Zr0.53,Ti0.47)O3 (PZT) was carried out. Because of the tendency of Zr4+-ions to hydrolyze and condensate extensively in water, the Zr4+
