  • Process for coating particles
    Publication number: 20030203207
    Abstract: The invention relates to a method for coating particles and particles thus obtained. According to the inventive method, the particles that are to be coated and at least one organo-metallic complex precursor of the coating material are brought into contact with each other in a liquid containing one or several solvents, whereby said particles are maintained in a dispersion in the liquid which is subjected to temperature conditions and supercritical pressure or slightly sub-critical pressure conditions; the precursor of the coating material is transformed in such a way that it is deposited onto the particles, whereupon the liquid is placed in temperature and pressure conditions so that it can eliminate the solvent in a gaseous state. The invention can be used to coat nanometric particles in particular.
