Abstract
A process for synthesizing particles of an oxide corresponding to a formula selected from: LiTiO; LiZTiO; and LiZTiO, said process including the steps of: a) preparing an intimately dispersed ternary mixture of TiO—LiY-carbon, wherein x is a number between 1 and 2, z is 1 or 2, Y is a radical chosen from the group consisting of CO, OH, O and TiOor a mixture thereof, and the carbon is a carbon powder selected from the group consisting of natural or artificial graphite, carbon black, Shawinigan black, Ketjen black and cokes; b) heating the dispersion at a temperature of between 400 and 1,000° C.; and c) if appropriate, adding a source of at least one metal Z to the ternary mixture, wherein the operating conditions are chosen in such a way as to yield a conversion of the initial products respectively into LiTiO, LiZTiO, LiZTiO.
