摘要:
以具有纤铁矿层状结构的钾锂钛氧化物为初始模板,通过原位拓扑反应制备出片状锐钛矿二氧化钛颗粒.以碳酸钡和片状二氧化钛为反应原料通过熔盐法制备了片状二钛酸钡颗粒.由于二氧化钛在氯化钠和氯化钾复合熔盐中的溶解速率大大低于碳酸钡,因而二氧化钛成为反应模板,反应产物二钛酸钡保留了二氧化钛的片状形貌.得到的片状二钛酸钡颗粒长20~50 μm,宽10~20 μm,厚约5 μm.
Abstract:
Platelike titanium dioxide (anatase) particles were prepared by in situ topotactic transformation reaction with potassium lithium titanium oxide as the template. Barium dititanate platelike particles were synthesized in a mixed sodium chloride and potassium chloride molten salt at 840 ℃ for 5 h with barium carbonate and the platelike titanium dioxide as precursors. As the dissolution rate of titanium dioxide is much lower than that of barium carbonate in the sodium chloride and potassium chloride molten salts, the platelike titanium dioxide particles react as templates. The obtained barium dititanate particles retain the plate-like morphology of the titanium dioxide precursors, and are 20-50 μm in length, 10-20 μm in width, and about 5 μm in thickness.
