The invention relates to ceramic powders coated with a layer of nanoparticles of various crystal structures, and to a method for their preparation. These coatings are prepared by introducing precursors into a water-in-oil emulsion, which, when decomposed during their detonation, form nanoparticles that adhere to the surface of the ceramic powder intended for coating. This basic ceramic powder can be synthesized during the detonation of a water / oil emulsion or directly placed in its composition. The properties of the obtained coating, such as thickness, adhesion, porosity and percentage of the coated surface, can be selected in accordance with the desired application, and ceramic powders coated can be used in various fields of nanotechnology, such as electronics, biomedicine, chemistry, ceramics and energy industry . |
