Abstract:
A method of producing high purity, low oxygen content titanium powder, comprising the steps ofobtaining crushed hydrided titanium powder with a desired percentage of particles of not more than a desired particle size; loading the crushed hydrided titanium powder as a layer onto a tray; heating the crushed hydrided titanium powder to between about 450Â° C. and about 500Â° C.; further heating the crushed hydrided titanium powder slowly over a period of between about four and five days under a partial vacuum to a temperature of between about 650Â°C. and about 700Â° C. to thereby dehydride the titanium powder; cooling the now dehydrided titanium powder still under the partial vacuum; placing the titanium powder under an inert atmosphere; and packaging the titanium powder in the inert atmosphere.
