Method for preparing tetragonal barium titanate powder
The invention discloses a method for preparing tetragonal barium titanate powder, which is specifically implemented by the following steps: 1) weighing 1.5-7.5 g of a chelating agent to prepare a chelating agent solution, 2) weighing 4.92-24.6 g of BaCl2 powder, and adding the BaCl2 powder into the chelating agent solution to obtain a mixed solution 1, 3) weighing 6.88-34.4 mL of butyl titanate, mixing the butyl titanate with absolute ethyl alcohol, and adding the mixture into the mixed solution 1 to obtain a mixed solution 3, 4) weighing 10-30 g of NaOH powder, and preparing a NaOH solution,5) adding the NaOH solution into the mixed solution 3 to obtain a mixed solution 4 of which the upper layer is clear and the lower layer is a white turbid solution, 6) carrying out rotary evaporationon the mixed solution 4 by using a rotary evaporator, carrying out alcohol washing on the obtained white precipitate, and drying in a drying oven to obtain white powder, and 7) carrying out high-temperature sintering on the white powder to obtain tetragonal barium titanate powder.
本发明公开了一种制备四方相钛酸钡粉体的方法，具体按照以下步骤实施：1)称取1.5‑7.5g螯合剂，制备螯合剂溶液；2)称取4.92‑24.6g BaCl粉体，加入到螯合剂溶液中，得到混合溶液1；3)量取6.88‑34.4mL的钛酸丁酯，与无水乙醇混合并加入到混合溶液1中，得到混合溶液3；4)称取10‑30gNaOH粉末，制备NaOH溶液；5)将NaOH溶液加入到混合溶液3中，得到上层澄清，下层为白色浊液的混合溶液4；6)使用旋转蒸发仪对混合溶液4进行旋蒸，对得到的白色沉淀进行醇洗，置于烘箱中干燥得到白色粉末；7)白色粉末进行高温烧结，即可得到四方相钛酸钡粉体。
