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+

A (Bi,La)4Ti3O12 acetate–citrate gel, prepared from an aqueous solution, was subjected to thermal decomposition in dry air and in inert atmosphere. In order to acquire the insight into its decomposition pathway, several hyphenated thermal analysis

The synthesis of multimetal oxides containing pentavalent elements like Nb and Ta out of an aqueous solution is very complicated due to the extremely high sensitivity of these metals towards hydrolysis. Moreover the only water-soluble starting compou

Aqueous sol-gel processing of pentavalent metals like Ta and Nb is very complicated since the only water soluble compound is the oxalate, which is not very suited for gel formation. Nevertheless, starting from Ta oxalate, it is possible to prepare a
