Method for preparing lead-free piezoelectric material and precursor solution
The present disclosure relates to a method for preparing a lead-free piezoelectric material and a precursor solution for preparing a precursor solution for a BZT-[alpha] BXT type ceramic wherein X is selected from Ca, Sn, Mn, and Nb, and [alpha] is a molar fraction selected in the range of between 0.10 and 0.90, the method comprises the steps of: a) dissolving at least one barium precursor compound and at least one precursor compound selected from the group consisting of a calcium precursor compound, a tin precursor compound, a manganese precursor compound, and a niobium precursor compound in a linear or branched chain anhydrous alkyl alcohol containing 2 to 6 carbon atoms and after dissolving; dehydrating by steam stripping to obtain a first solution; b) dissolving at least one zirconium precursor compound and at least one titanium precursor compound in a linear or branched anhydrous alkyl alcohol containing 2 to 6 carbon atoms in the presence of an anhydrous chelating agent to obtain a second solution; c) combining the first solution and the second solution in an anhydrous environment and dewatering by stripping to obtain a precursor solution.
本公开涉及一种用于制备无铅压电材料和前体溶液的方法，用于制备用于BZT‑αBXT型陶瓷的前体溶液，其中X选自Ca、Sn、Mn和Nb，并且α是在0.10与0.90之间范围内选择的摩尔分数，该方法包括以下步骤：a)通过将至少一种钡前体化合物和选自由钙前体化合物、锡前体化合物、锰前体化合物和铌前体化合物组成的组中的至少一种前体化合物溶解于含有2到6个碳原子的直链或分支链无水烷基醇中并且溶解之后，通过汽提进行脱水以获得第一溶液；b)在无水螯合剂存在下将至少一种锆前体化合物和至少一种钛前体化合物溶解于含有2到6个碳原子的直链或分支链无水烷基醇中，以获得第二溶液；c)在无水环境中结合第一溶液和第二溶液并通过汽提进行脱水，以获得前体溶液。
