摘要

A particulate mixture which can be used as a precursor of lithium transition metal silicate-type compound of small particle size and low crystallinity, is provided. It is a mixture of silicon oxide particulates, transition metal oxide particulates, and lithium transition metal silicate particulates, and its powder X-ray diffraction measurement shows diffraction peaks near 2&thetas;=33.1° and near 2&thetas;=35.7°, and said silicon oxide particulates and said transition metal oxide particulates are amorphous, and said lithium transition metal silicate particulates are in a microcrystalline or amorphous state.
