Abstract
Lithium manganese spinel Li1+yMn2-yO4 (0.0 less than or equal to y less than or equal to 0.07) synthesized by the sol-gel process is studied with a focus on the effects of the changes of formation conditions which can sensibly determine the mean crystallite size from a few nanometers to several hundred nanometers. Changes of stoichiometry and abundance of the spinel phase can be observed in the 573 less than or equal to T-A (K) less than or equal to 1073 range of annealing temperature (T-A). Comparing spinel phases obtained by sol-gel and solid state synthesis evidences the correlation among composition, structure, and electric and magnetic properties. (C) 1999 Academic Press.
