Method for preparing barium zirconate titanate nano ceramic coating structure based on hydrothermal method
The invention relates to the technical field of barium zirconate titanate nano ceramics, in particular to a method for preparing a barium zirconate titanate nano ceramic coating structure based on a hydrothermal method. The preparation method comprises the following steps: uniformly mixing a tetrabutyl titanate solution with a tetrabutyl zirconate solution, then uniformly mixing with a barium acetate solution to obtain a mixed solution, and drying to obtain xerogel; performing hydrothermal reaction on the dry gel and a mineralizing agent, and drying to obtain nano powder; and finally, adding the nano powder into the mixed solution, and subsequently carrying out hydrothermal treatment and centrifugal washing treatment to obtain the barium zirconate titanate nano ceramic coating structure. According to the method for preparing the barium zirconate titanate nano ceramic coating structure based on the hydrothermal method, the research process of microstructure regulation of a lead-free piezoelectric ceramic system is greatly promoted, and the method has important significance on deep exploration of electrocaloric, ferroelectric, dielectric and other properties of piezoelectric ceramics and widening of the application field of the piezoelectric ceramics.
本发明涉及锆钛酸钡纳米陶瓷技术领域，尤其是涉及一种基于水热法制备锆钛酸钡纳米陶瓷包覆结构的方法。本发明将钛酸四丁酯溶液与锆酸四丁酯溶液混匀，然后与醋酸钡溶液混匀得到混合溶液，干燥处理得到干凝胶；然后将干凝胶与矿化剂水热反应后干燥得到纳米粉；最后将纳米粉加入上述混合溶液中，后续经水热处理及离心洗涤处理，得到锆钛酸钡纳米陶瓷包覆结构。本发明的一种基于水热法制备锆钛酸钡纳米陶瓷包覆结构的方法将大大推动无铅压电陶瓷体系微结构调控的研究进程，对压电陶瓷电卡、铁电及介电等性能的深入探究以及其应用领域的拓宽具有重要意义。
