Abstract

A novel approach was applied to synthesize B6O using CaB6 and B2O3 powders as reactants. CaB6 and B2O3 were reacted to generate B6O and CaB2O4 at 1573 K, and the by‐product CaB2O4 was removed by acid leaching. It was found that the samples prepared in this work were oxygen deficient (B6Ox, x ≈ .76–.77). The optimal molar ratio of CaB6 to B2O3 was determined to be 3:5, and excess B2O3 could not lead to a change in the value of oxygen occupancy. Scanning electron microscope images showed that regular holes similar to the morphologies of CaB6 particles were exhibited in the final samples, which could be explained by the diffusion of CaB6 during the reaction process.

通过 CaB6 和 B2O3 反应合成 B6O 粉末的新路线

以 CaB6 和 B2O3 粉末为反应物合成 B6O 的方法很新颖。CaB6 和 B2O3 在 1573 K 下反应生成 B6O 和 CaB2O4，副产物 CaB2O4 通过酸浸去除。结果发现，这项工作制备的样品缺氧（B6Ox，x ≈ .76-.77）。确定 CaB6 与 B2O3 的最佳摩尔比为 3:5，过量的 B2O3 不会导致氧占有率值的变化。扫描电子显微镜图像显示，最终样品中出现了与 CaB6 颗粒形态相似的规则孔洞，这可以解释为反应过程中 CaB6 的扩散。
