Abstract

The technological possibilities for the synthesis of barium-titanate phases were investigated by applying mechanochemical activation (from 30 min. to 2 h) of the starting charges and thermal treatment of the compositions up to 900°C (with an isothermal delay of 1 h). The applied laboratory regime for the preparation of the experimental samples is in accordance with the preliminary thermodynamic calculations. The identification of the obtained phases was carried out by X-ray phase analysis (XRD). Based on the experimental results, the necessary technological conditions for the synthesis of titanate monophasic product by heat treatment at lower temperature values than those typical for standard classical synthesis have been established. The potential possibilities of application of the synthesized phases for the deposition of thin layers on metal surfaces and the preparation of various coatings with different functional purposes are considered.
