Abstract
A method for improved atomization of molten metal having a melting point above 1000.degree. C. is taught. The atomization is carried out in close coupled atomizer. The melt to be atomized is supplied from a reservoir where it is heated to a temperature slightly above the melting point. The molten metal from the reservoir is guided to the atomization zone by a ceramic melt guide tube. The atomization is accomplished with the aid of a shallow draft atomizing nozzle. The melt in the melt guide tube is heated with the aid of an induction coil which is disposed thereabout and between the reservoir and the shallow draft gas nozzle.
