Abstract (en)

[origin: EP1500639A2] Powder comprising cores of a first material coated with a binder layer containing nanoparticles of a second material is new. An independent claim is also included for producing a powder as above by preparing a solution of the binder in a first solvent (S1), preparing a bath of carrier liquid immiscible with S1, dispersing particles of the first material in the bath, adding nanoparticles of the second material while stirring the bath, adding the binder solution, adding a surfactant, stirring, removing S1 by washing with a second solvent, and filtering and/or drying the resulting powder.
