Method for improving energy storage characteristic of barium titanate-based ceramic by using donor-acceptor composite doping
The invention discloses a method for improving the energy storage characteristic of barium titanate-based ceramic by using donor-acceptor composite doping, and relates to the technical field of material preparation. The method comprises the following steps: weighing BaCO3, TiO2, MnCO3 and Nb2O5 powder, mixing the BaCO3, TiO2, MnCO3 and Nb2O5 powder by using a medium, grinding to obtain first slurry; drying and sieving the first slurry, sintering the obtained mixed powder to obtain synthesized first powder; sieving the first powder, grinding to obtain second slurry; drying and sieving the second slurry, adding PVA glue to obtain second powder with a particle size of 60-100 meshes, pressing the second powder into a rough blank by using a tablet press; and sintering the rough blank to obtaina barium titanate-based ceramic sample. The method has the advantages that (1) the raw materials used in the preparation method are non-toxic and environment-friendly, and environmental pollution is not easily caused during preparation and subsequent recovery treatment; and (2) the energy storage efficiency of the barium titanate-based ceramic prepared by the preparation method is higher and can reach 86%.
本发明公开了一种使用施主‑受主复合掺杂提高钛酸钡基陶瓷储能特性的方法，涉及材料制备技术领域，包括：称量BaCO3、TiO2、MnCO3、Nb2O5粉末并使用介质混合后研磨得到第一浆料；将第一浆料烘干后过筛，将得到的混合粉末烧结得到合成第一粉料；将第一粉料过筛后研磨后得到第二浆料；将第二浆料烘干过筛后加入PVA胶获得粒径在60‑100目之间的第二粉料，并使用压片机将所述第二粉料压成粗坯；将粗坯烧结得到钛酸钡基陶瓷样品。本发明的优势在于：(1)本发明的制备方法所用的原料无毒环保，制备和后续回收处理时不易造成环境污染；(2)本发明的制备方法制备的钛酸钡基陶瓷的储能效率更高，可达86％。
