Abstract
PURPOSE:To produce a metal powder having high purity and crystallinity by dissolving and dispersing fine metal oxide powder into an org. solvent of a specific b. p. and holding this liquid suspension in a hydrogen atmosphere for a prescribed period of time at the temp. below the b. p. of the solvent. CONSTITUTION:The fine powder of the metal oxide or metal hydroxide of copper, silver, platinum, etc., is dissolved and dispersed in the org. solvent having >=100 deg.C b. p. Ethylene glycol or glycerol or the deriv. thereof is preferably used for the org. solvent. This liquid suspension of the org. solvent is held in the hydrogen atmosphere for the prescribed period of time at the temp. below the b. p. thereof. The fine metal powder of a polyhedral shape having good crystallinity is thus obtd. by the relatively simple operation. This fine metal powder is less surface-oxidized and is hardly oxidized at ordinary temp.
