摘要：

Barium zirconate BaZrO3 has been prepared via heating of equimolar mixture of BaCO3 with ZrO2 at 900–1050°C with and without preliminary mechanical activation of the reactants. Degree of BaZrO3 formation has been analyzed using basic equations of kinetics of solid-phase reactions in comparison with analogous synthesis of strontium and calcium zirconates. The relative efficiency of mechanical activation in the zirconates synthesis follows the Ca > Sr ≈ Ba series.
