一种BaTaO2N氧氮化物粉体及其双氮源制备方法
本发明公开了一种BaTaO2N氧氮化物粉体的双氮源制备方法，包括以下步骤：S1、将碱土金属盐、钽盐与氮源I溶于醇中，球磨后干燥，得到混合前驱体；S2、将步骤S1所得的混合前驱体与氮源II置于反应容器中，在保护气氛中煅烧，得到BaTaO2N氧氮化物粉体；其中，所述混合前驱体与氮源II间隔设置。本制备方法制备周期短，得到的产物纯度高、介电性能好。
The invention discloses a double-nitrogen source preparation method of BaTaO2N oxynitride powder. The method comprises the following steps: S1, dissolving an alkaline earth metal salt, a tantalum saltand a nitrogen source I in alcohol, and carrying out ball milling and drying to obtain a mixed precursor; S2, putting the mixed precursor obtained in the step S1 and a nitrogen source II into a reaction container, and calcining in a protective atmosphere to obtain the BaTaO2N oxynitride powder; the mixed precursor and the nitrogen source II are arranged at intervals. The preparation method disclosed by the invention is short in preparation period; the obtained product is high in purity and good in dielectric property.
