摘要
对Li_2O-(Mg、Zn、Ni)O-V_2O_5三元体系在500—800℃相图的研究表明,在每个系统内部都出现了一个依端员组分摩尔比为1:2:1的化合物。即橄榄石型的LiMgVO_4,硅铍石型的LiZnVO_4和尖晶石型的LiNiVO_4。不同的是,Li_2O-MgO-V_2O_5中发现了第二个三元相和一个固溶体。LiO_2-NiO-V_2O_6中得出一个固溶体,而LiZnNO_4中未得固溶体。
The phase relations were determined in the systems of Li_2O-(Mg, Zn, Ni) O-V_2O_5 at the temperatures ranging between 500 and 800℃. Each of the ternary systems is characterized by an orthovanadate: olivine-type LiiMgVO_4, phenakite-type LiZnVO_4, and spinel-type LiNiVO_4. Differences between them lie in the fact that there are two ternary phases in the system (Li_2O-MgO-V_2O_5 and none solid solution in the system (Li_2O-ZnO-V_2O_5).
