dc.description.abstractCurrent technological and scientific challenges have encouraged the search for a simple and energy-efficient method to synthesis fine product particles with desirable morphology and properties. The submicro-spheres of perovskite barium zirconate (BaZrO<inf>3</inf>) in this study were synthesized successfully via the soft-mechanochemical method under ambient conditions, without surfactants or any capping agents. The synthetic mechanism model was proposed as being time-dependent. The hydrolysis, nucleation (crystallization) and growth of particles via Ostwald ripening were discussed deeply. Mechanical energy not only afforded a local high temperature to activate the chemical reaction and diffusion rate of particles, but also prevent aggregation and agglomeration by homogeneous mechanical stirring. Nevertheless, as-prepared BaZrO<inf>3</inf> powders exhibited properties of photoluminescence (PL) with green emission from lattice formation defects. Dielectric properties and the quality factor (Q-factor) were investigated as well. It was notable that the soft-mechanochemical method can provide a high yield and enable work that is environmentally friendly.
