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+

Looking at its vast range of applications, nanostructured ZnO can be considered as a key technological material. Simple and ecological production techniques for this and other nanostructured materials can boost the detection of their unusual properti

Phase pure RUO 2 and SrRuO 3 powders were obtained by a water-based solution-gel route. By reacting ruthenium(III)acetylacetonate with H 2 O 2 in a citric acid solution, a stable aqueous Ru-precursor solution could be prepared. An aqueous Sr-precurso

A new aqueous solution-gel route for the synthesis of ferroelectric lanthanum substituted bismuth titanate was developed, based on aqueous Bi 3+ - and La 3+ -citrate solutions and an aqueous peroxocitrato-Ti(IV) solution. A homogeneous, amorphous pre

Sr0.9Bi2.2Ta2O9 thin films were prepared on a Pt-substrate by aqueous chemical solution deposition. The applied heat treatment seems to have a significant influence on the ferroelectric response, crystallinity and surface morphology. For two-layer th

An aqueous chemical solution deposition method was used to prepare thin films of ZnO on SiO2/Si (1 1 1) substrates. Starting from an aqueous solution of Zn acetate, citric acid and ammonia, very thin films could be deposited by spin coating. Heating

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

Bismuth titanate (Bi4Ti3O12) was synthesized by an aqueous solution-gel process starting from solutions of bismuth acetate and a peroxocitrato-Ti(IV) complex. To gain insight into the thermal decomposition pattern of the gel several thermal analysis

The synthesis of nanoparticulate ZnO via an aqueous carboxylate gelation route is presented. Starting from a solution of zinc acetate with citric acid as a complexing agent, a solid glassy gel is obtained after drying that is converted into a fine po
