Phase Equilibria in the Li2O–Al2O3–Ni–Co–O System
— This paper presents a topological analysis of phase equilibria in the Li 2 O–Al 2 O 3 –Ni–Co–O system. Using the fragmentary experimental data available, we construct isothermal phase diagrams of the Li 2 O–Al 2 O 3 –Nc–O (Nc = Ni + Co) and Li 2 O–Al 2 O 3 –NiO 1 + x –CoO 1 + x (0 ≤ x < 1) syst...
