Process for the preparation of nano-and micro-particles of group II and transition metals oxides and hydroxides, the nano-and micro-particles thus obtained and their use in the ceramic, textile and paper industries

摘要

A process for the preparation of particles of group II and transition metals oxides and hydroxides is described, which provides a homogeneous phase synthesis step by a double exchange reaction and, in the case of oxides, the subsequent calcination of the corresponding hydroxides; the particles thus obtained and their use for surface coatings of ceramic, textile and paper materials are also described.
