The present invention relates to a precursor solution for the preparation of ceramics of the BZT-αBXT type, wherein X is selected from Ca, Sn, Mn and Nb, and α is a mole fraction selected in the range between 0.10 and 0.90, said solution comprising: 1) at least one barium precursor compound; 2) a precursor compound selected from at least one calcium compound, at least one tin compound, at least one manganese compound and at least one niobium compound; 3) at least one zirconium-free 4) at least one anhydrous titanium precursor compound; 5) a solvent selected from polyols and polyol mixtures, and an auxiliary solvent selected from alcohols, carboxylic acids, esters, ketones, ethers, and mixtures thereof and 6) chelating agents. The invention also relates to a method for preparing the precursor solution, a piezoelectric material obtained from the precursor solution, a method for preparing a film of the piezoelectric material, a device comprising the piezoelectric material and the use of the piezoelectric material. |
