AB  - Freeze-drying, as a cryochemical powders processing method is applied in ZnO submicrometar to nanosized powders synthesis. The process involves rapid freezing of the sprayed precursor solution, drying under vacuum by sublimation of the solvent and the salt decomposition to oxide by thermal treatment. The precursor salt for ZnO powder synthesis was Zn(NO3)2·6H2O dissolved in distilled water (1 mol/dm3). The aqueous solution was sprayed by the twin-fluid atomization system, frozen using liquid nitrogen and dehydrated using a freeze-dryer operated at the temperatures from 243 K to 293 K and vacuum from 13 Pa to 20 Pa. A detailed X-ray analysis of the microstructure parameters such as the average crystallite sizes and shapes, crystal lattice microstrains and stacking faults of ZnO produced by thermal decomposition of as prepared Zn(NO3)2 at temperatures of 548 K and 898 K is realized by the pattern decomposition technique. The dependence between microstructural parameters and temperatures of thermal decomposition has been established.

AB  - The influence of urea on the formation process in the Bi-Pb-Sr-Ca-Cu-O system, as well as, on the final high Tc. phase content and morphology of the powders obtained by spray pyrolysis method was studied. The process involves aerosol formation from common nitrate solutions (with and without urea addition) using ultrasonic atomizer operated at 1.7 MHz and control over aerosol decomposition up to 840°C. It was shown that the presence of urea in the precursor solutions promotes a faster phase transformation, improves homogeneity, reduces substantially the mean particle size and affects the resulting morphology of powders. © 2000 Elsevier Science S.A.
