Title: Process for making titanium, zirconium and hatnium-based metal particles for powder metallurgy

Abstract

A process to produce passified Group IVb transition metal based metal particles having a controlled particle size distribution is disclosed which produces particles suitable for metallurgy usage without additional particle size reduction. Such particles are also substantially free of halides and are produced at temperatures considerably below that of arc melting temperatures of Group IVb transition metals and alloys based thereon.
