Preparation method of monodisperse nano-scale barium titanate powder with controllable crystal phase
The invention discloses a preparation method of monodisperse nano-scale barium titanate powder with a controllable crystal phase, which adopts a microwave-assisted hydrothermal method for preparation and can controllably synthesize nano-scale barium titanate powder with different crystal phases. According to the preparation method of the monodisperse nano-scale barium titanate powder with the controllable crystal phase, controllable synthesis of the monodisperse nano-scale barium titanate powder with different crystal phases (smaller than 200nm) can be achieved through the synergistic effect of citric acid and oleic acid, the whole preparation process is simple, raw materials are easy to obtain, the equipment requirement is not high, the cost is low, and the preparation method is suitable for industrial production. The industrial production requirements can be met.
本发明公开了一种单分散、晶相可控的纳米级钛酸钡粉体的制备方法，采用微波辅助水热方法制备，能够可控合成不同晶相的纳米级钛酸钡粉体。本发明的一种单分散、晶相可控的纳米级钛酸钡粉体的制备方法利用柠檬酸和油酸的协同作用，可以实现单分散、不同晶相且纳米级（200nm以下）的钛酸钡粉体的可控合成，且整体制备流程简单、原料易获取、设备要求不高且成本低廉，能够满足工业生产需求。
