Abstract
A short review is given on the particular phenomena of abstracting lattice oxygen by conventional hydrocarbon under mechanical stressing. The process can be regarded as a reduction process similar to a traditional hydrometallurgy. However, the mechanochemical process can be regarded as a tool for introduc-ing oxygen vacancies and enables to acquire suboxides or the oxide with lower oxidation number, when we deal with transition metal oxides. Case studies on SiO2 and V2O5, based on our recent experimental studies.
