  • Method for producing a coating on the surface of a particle or material, and corresponding product
    Publication number: 20060263627
    Abstract: The invention relates to a method for producing at least one coating (3) on at least one section (4) of the surface of a body (2) by the chemical conversion of at least one constituent of the body into at least one constituent of the coating. The method is characterised in that a chemical, non-metallic compound forms the constituent of the body. The method can be described as an “intrinsic” coating method, as the coating process is not carried out by the external application of material to the surface section, but by the material conversion of the constituent of the body. The method permits the production of a body comprising at least one surface section with at least one coating that has been formed by the chemical conversion of at least one constituent of the body into at least one constituent of the coating.
