In this region, powders were obtained by chemical precipitation during various precipitation times from aqueous solutions. X-ray diffraction was used to track the growth of the CdS nanophase of a disordered structure and hexagonal Cd(OH)2 phase consumption with time. It was found by complexonometry that part of cadmium formed insoluble structures as a result of the formation of continuous nanosized CdS shells on single crystalline Cd(OH)2 particles. A comparative analysis of the experimental data was used to determine the kinetics of formation of nucleus–shell Cd(OH)2/CdS particles in the system Доп.точки доступа: Vorokh, A. S.; Kozhevnikova, N.
