摘要: Abstract Purity and synthesis temperature of nanocrystals are key challenges facing the scientific community. Herein a novel solid-state approach to synthesize fine BaTiO 3 with narrow size distribution using high-speed ball-milling process is reported. In order improve kinetics this reaction, starting materials, BaCO TiO 2 , were milled for 10 h before mixing initiating reaction. The contribution step formation analyzed by XRD diffractometry FE-SEM techniques. It was found that use mechanically activated materials favors decomposition at low temperatures improves Ba 2+ diffusion through formed layer. consequence, very free from secondary phases obtained lower in contrast previous works.
