LOWTEMPERATURE NANO-SCALE POWDERSYNTHESIS OF THE PHASES IN THE SYSTEM PbTiO3 – BiScO3
New piezoelectric phases PbTiO3 – BiScO3 system were prepared by using chemical assembly method. Final products were formed in reaction between gel composition, including TiO2·xH2O, Sc2O3·yH2O, hydroxides Pb(II) and Bi(III). The results of X-ray diffraction show that the powders have a single phase (cubic or tetragonal)perovskite structure. Technologies of manufacturing nano- and ultradisperse powders of the phases under consideration by the chemical assembly methods, influence of synthesis conditions upon crystal structure and some properties have been discussed.
