SYNTHESIS OF YTTRIUM AND CALCIUM STABILIZED ZIRCONIA BY CONTROLLED DOUBLE-JET PRECIPITATION

The work is aimed at obtaining yttrium and calcium stabilized zirconia with a spheroidal particle shape and a narrow particle size distribution. It was shown that the stabilizing com-ponents have a different effect on the morphology and particle size distribution of the obtained oxides

SYNTHESIS OF CdS FILMS ON GLASS BY THE AMMONIA-ALKALINE SCHEME

This work is aimed at finding optimal conditions for the synthesis of CdS films in order to obtain films of controlled thickness and high homogeneity. The presence of Cd(OH)2 in the synthesized films was revealed. The optimal parameters for the synthesis of CdS films are found

STUDY OF PHOSPHATES SORPTION BY ZIRCONIUM OXIDE POWDERS FROM AQUEOUS SOLUTIONS

The ability of zirconia oxide powders to remove phosphates from water was studied. The experimental data fitted well with the Langmuir model isotherm. Theoretical maximum adsorption capacity for P was estimated to be 36,3 mg/g. This adsorption capacity was compared with other similar materials

INVESTIGATION OF THE CONTROLLED TWO-JET PRECIPITATION PROCESS OF HYDRATED ZIRCONIA

The controlled two-jet precipitation process of hydrated zirconia was studied. Particle size experimental information were analyzed using population balance. It was found that hydrated zirconia synthesized at pH = 3 and pH 5 has two populations, and at pH = 8 it has only one population
