Abstract
A method for producing a powder by pulverizing a stream of molten metal using a pulverization gas, which directly hits the molten metal stream, whereby a) a reactive gas is used as the pulverization gas such that a compound is formed by the reaction of the pulverization gas with the metal or an alloy component thereof and b) the temperature of the pulverization gas and the cooling speed are set such that the metal or the alloy component thereof is converted into the compound, to a substantial degree completely, in one step.
