Abstract	本发明公开了一种钛酸锶钡纳米粉体的制备方法，包括：按目标复合金属化合物元素化学计量比称取金属化合物原料，而后与燃烧剂和溶剂混合，充分溶解，制备前驱体溶液；然后对前驱体溶液进行浓缩制备前驱体凝胶；再将前驱体凝胶雾化成液滴，而后将雾化液滴通入加热装置中发生自蔓延燃烧反应。以上方法工序简单，对设备要求低，能耗小，成本低；且反应速度快，产率高，所制得钛酸锶钡纳米粉体的比表面积高，分散性好，产物粒径小，晶相均一，粉体纯度高。
Other Abstract	The invention discloses a preparation method of barium strontium titanate nano powder. The preparation method comprises the following steps: weighing a metal compound raw material according to a target composite metal compound element stoichiometric ratio, then mixing the metal compound raw material with a combustion agent and a solvent, and fully dissolving the metal compound raw material to prepare a precursor solution; concentrating the precursor solution to prepare precursor gel; and atomizing the precursor gel into liquid drops, and feeding the atomized liquid drops into a heating deviceto generate a self-propagating combustion reaction. The method is simple in process, low in equipment requirement, low in energy consumption and low in cost; and the reaction speed is high, the yieldis high, and the prepared barium strontium titanate nano powder has high specific surface area, good dispersity, small product particle size, uniform crystal phase and high powder purity.
