Barium titanate powder as well as preparation method and application thereof
The invention belongs to the field of preparation of nano ceramic powder, discloses barium titanate powder and a preparation method and application thereof, and aims to solve the technical problems of large particle size, wide distribution and poor dispersibility of barium titanate powder, and the preparation method comprises the following steps: (1) preparing a barium salt solution; (2) taking anatase titanium dioxide obtained by calcining a titanic acid nanotube as a titanium source, and adding the anatase titanium dioxide into the barium salt solution to obtain a barium titanate precursor solution; (3) carrying out hydrothermal reaction on the precursor solution; and (4) carrying out suction filtration, washing, drying and grinding to obtain barium titanate powder. The barium titanate prepared by the method has the characteristics of small particle size, narrow distribution and good dispersity; meanwhile, the reaction can avoid the use of a large number of mineralizing agents, the method is low in cost, good in safety and simple in process, large-scale production of the powder can be achieved, and the development requirements of subsequent small-size products of multilayer ceramic capacitors are met.
本发明属于纳米陶瓷粉体制备领域，公开了一种钛酸钡粉体及其制备方法和应用，用以解决钛酸钡粉末的粒径尺寸较大、分布较宽、分散性差的技术问题，步骤如下：（1）配置钡盐溶液；（2）以钛酸纳米管经过煅烧处理得到的锐钛矿二氧化钛为钛源，将其加入到钡盐溶液中，得到钛酸钡前驱体溶液；（3）前驱体溶液水热反应；（4）进行抽滤、洗涤、干燥及研磨得到钛酸钡粉体。本发明制备的钛酸钡具有颗粒尺寸小，分布窄、分散性好的特点；同时该反应可以避免使用大量的矿化剂，该方法成本低、安全性好、工艺简单、亦可实现粉体的大规模生产，满足后续多层陶瓷电容器小尺寸产品的开发要求。
