一种纳米BaTi1-xSnxO3粉体的制备方法
本发明属于新型纳米材料技术领域，更具体地，涉及一种纳米BaTi1‑xSnxO3粉体的制备方法。以四氯化钛、氯化钡、氯化锡为原料，以马来酸为沉淀剂，经滴定沉淀反应、液相均匀反应、洗涤过滤、冷冻干燥、热分解等步骤后制备得到纳米四方相钛酸钡或锡掺杂钛酸钡粉体。制备得到的Sn掺杂BaTiO3粉体可以满足不同掺杂浓度的需求，分散性好，纯BaTiO3的c/a大于1.006，粒径在44nm到200nm之间，均匀可控。
The invention belongs to the technical field of novel nano materials, and particularly relates to a preparation method of nano BaTi (1-x) SnxO3 powder. The preparation method comprises the following steps: by taking titanium tetrachloride, barium chloride and tin chloride as raw materials and maleic acid as a precipitator, carrying out titration precipitation reaction, liquid-phase homogeneous reaction, washing and filtering, freeze-drying, thermal decomposition and the like, thereby obtaining the nano tetragonal-phase barium titanate or tin-doped barium titanate powder. The prepared Sn-doped BaTiO3 powder can meet the requirements of different doping concentrations and is good in dispersity, the c/a of pure BaTiO3 is larger than 1.006, the particle size ranges from 44 nm to 200 nm, and uniformity and controllability are achieved.
