ABSTRACT:
A method of atomization of metals which melt at high temperatures is provided. The atomization is carried out in an atomization zone at the lower end of a melt delivery tube. Melt is delivered to the zone through the tube. Atomizing gas is delivered to the melt emerging from the lower end of the melt delivery tube by impinging the gas inwardly against the outer tapered end of the melt delivery tube. The tube's outer surface is formed with a concavity so that the incident atomizing gas is deflected into contact with the emerging melt stream.
