Abstract
This invention relates to an apparatus for production of metal powders of a low oxygen content, which are preferred as raw material powders for sintered bodies of a high toughness, according to the water atomizing method. More specifically, when a molten metal is sprayed in a limited space with use of a liquid crystal medium and cooled promptly, a metal powder results of a good moldability which has an oxygen content corresponding to 1/2 or less of the oxygen contents of metal powders prepared by conventional apparatuses and which is excellent in the size uniformity.
