Abstract—

This paper presents a topological analysis of phase equilibria in the Li₂O–Al₂O₃–Ni–Co–O system. Using the fragmentary experimental data available, we construct isothermal phase diagrams of the Li₂O–Al₂O₃–Nc–O (Nc = Ni + Co) and Li₂O–Al₂O₃–NiO_{1 + x}–CoO_{1 + x} (0 ≤ x < 1) systems. Data are presented on phase equilibria involving Li(Ni,Co,Al)O₂ (α-NaFeO₂ structure), (Li,Ni,Co,Al)Al₂O₄ (spinel structure), (Li,Ni,Co)O (rock-salt structure), and (Li,Ni,Co)₃O₄ (spinel structure) solid solutions, whose homogeneity regions are evaluated.

Li 2 O–Al 2 O 3 –Ni–Co–O系统中的相平衡

摘要-

本文介绍了Li ₂ O–Al ₂ O ₃ –Ni–Co–O系统中相平衡的拓扑分析。利用现有的部分实验数据，我们构建了Li ₂ O–Al ₂ O ₃ –Nc–O（Nc = Ni + Co）和Li ₂ O–Al ₂ O ₃ –NiO _{1 + x} –CoO _1的 等温相图。_{+ x}（0≤x <1）系统。数据被呈现在涉及锂（镍，钴，铝）O相平衡₂（α-NaFeO ₂结构），（李，镍，钴，铝）的Al ₂ ö ₄（尖晶石结构），（Li，Ni，Co）O（岩盐结构）和（Li，Ni，Co）₃ O ₄（尖晶石结构）固溶体，评估其均质区域。
