Karla Marksa 68, Kazan, 420015 Tatarstan, Russia *e-mail: alina17xaj@mail.ru Received April 17, 2018; revised September 15, 2018; accepted October 15, 2018 Abstract—We have studied the morphology and phase composition of precursors for the preparation of highly dispersed alumina-based Al O –ZrO –MgO materials. The precursors were synthesized in a coaxial dia- 2 3 2 phragmless electrolyzer with a soluble anode. Zr(IV) and Mg(II) ions were added during the synthesis pro- cess. It has been shown that varying electrolysis conditions allows the particle size and phase composition of the precipitate to be controlled. Synthesis in the Al O –ZrO –MgO system is accompanied by Al MgO spi- 2 3 2 2 4 nel formation. Increasing the spinel concentration helps the metastable phase θ-Al O to persist. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Inorganic Materials Springer Journals
