Patent abstract
A method for producing particle shaped material from a melt. The method comprises the following steps: the material is melted, the material melt is intimately mixed with a gas in a predetermined ratio; the gas-liquid mixture is suddenly expanded and the material powder thus produced is collected, which the other gas is added to according to a predetermined air/liquid ratio during the expansion with solidification of the formed material drop, to form a material powder having a controlled size distribution and shape in an area of lower pressure than the gas/liquid mixture.
