摘要：

The weight and plaque diameter change following thermal treatment, and the density and lattice constant of lithium-rich LixNi1-xO solid solutions obtained by heat treatment at 750-degrees-C of Li2CO3-LiyNi1-yO(y < x) mixtures were measured as a function of time. It was found that densification of the solid solutions depends on the method of obtaining the Li2CO3-LiyNi1-YO mixtures. When a large amount of carbonate is put into the starting mixtures Ni-Li2CO3-binder, and the powders are milled togther, sintering occurs; in contrast, when the carbonate is added after the formation of LiyNi1-yO solid solution, so that the interstices of the plaque are filled with molten carbonate, the resulting mixtures exhibit no densification. For densification to Occur, Li2CO3 must be in intimate contact with the lithium-doped NiO grains.
