<p>PURPOSE: To obtain modified metal powder by mechanochemically reacting metal powder with a modifying substance such as an organic thiol compound, a free radical-reactive compound, an addition reactive compound, etc., under grinding conditions to cause new faces on metal particles, excellent in dispersibility, useful as a paste, etc. CONSTITUTION: Metal powder such as palladium powder produced by a wet method is mixed, ground and mechanochemically reacted with at least one modifying substance such as an organic thiol compound (e.g. octadecylthiol, etc.), a free radical-reactive compound (e.g. styrene, etc.), an addition reactive compound (e.g. novolak, etc.) etc., in a zirconia pot under grinding conditions to cause new faces on metal particles to give the objective modified metal powder dissociating the aggregated metal particles, containing a lipophilic group on the surface of the metal powder, being chemically and extremely stable, excellent in dispersibility and useful as a paste for a thick film, etc.</p> |
