【摘要】 本文采用化学浸出、真空热蒸发锂和增加配料中硼含量的方法制备出了缺锂状态的LiB化合物.通过XRD分析,发现缺锂后主要引起晶胞参数c增大,并呈阶跃式的变化,由原来富锂状态的c=0.2796nm变到0.2886nm、0.2981nm和0.3118nm.将缺锂状态的LiB化合物放入液体锂中处理后,可以恢复成富锂状态。文中对衍射数据进行了分析计算,讨论了晶体结构模型的问题,并观察了缺锂状态LiB化合物的形貌。更多还原

【Abstract】 LiB compound lacking lithium has been prepared through soaking lithium-rich LiB compound in solution ofdry naphthalene dissolved in anhydrous tetrahydrofuran and heating in vacuum to extract lithium from LiB compoundand increasing B content in raw materials. By means of XRD analysis, it is discovered that lithium-lacking leads tolattice parameter c increasing evidently and jumping stage by stage, from 0.2796nm for lithium-rich LiB compound to0.2886nm, 0.2981nm, 0.3118nm for lithium-lacking LiB compound. If lithium-lacking LiB compound is heated inmelting lithium, it will retum to lithium-rich LiB compound. Diffraction data and crystal structure model wereinvestigated and morphology of lithium-lack LiB compound was observed.更多还原
