Abstract (en)

[origin: WO8600610A1] Passified Group IVb transition metal-based metal particles having a controlled particle size distribution suitable for metallurgy usage without additional particles size reduction and process for making the same. Such metal particles are substantially free of halides, hydrogen, oxygen, nitrogen and carbon and are produced at temperatures considerably below that of arc melting temperatures of Group IVb transmission metals and alloys based thereon.
