Claim Text:
1. Process for preparing a ceramic powder coated with a nanoparticle layer comprising: introducing in a water-in-oil (W/O) emulsion at least a precursor that is either in a solid state or dissolved in the W/O emulsion, and then detonating the W/O emulsion such that during the detonation stage, the precursor decomposes to synthesize nanoparticles (b), which are deposited on a base ceramic particle (A), forming a coating layer of nanoparticles (b), wherein the base ceramic particle (A) is either synthesized during the W/O emulsion detonation stage or added and homogenized in the W/O emulsion prior to the detonation stage, wherein a detonation temperature of the detonation stage is less than 800° C.
