The Armstrong Process ® is a novel powder production process capable of producing commercially pure titanium and Ti6Al4V by the reduction of titanium tetrachloride and other metal halides by sodium. The process produces powder particles with a unique, low bulk density, "corallike" morphology.
The HAMR Ti powder consistently meets the purity requirements defined by the industry standard and our team has developed a reliable recipe for pilot scale production of HAMR Ti powder. A detailed energyeconomic analysis and a full process simulation were performed to estimate the energy consumption, emissions, and cost at mass production.
SELECTIVE CHLORINATION OF TITANIUM ORE AND PRODUCTION OF TITANIUM POWDER BY PREFORM REDUCTION PROCESS (PRP) H. Zheng* and Okabe* Institute of Industrial Science, The University of Tokyo. 461 Komaba, Meguroku, Tokyo, Japan. ABSTRACT
Abstract. To develop an effective process for titanium powders production, a calciothermic reduction process of pigment titanium dioxide (w(TiO 2)>98%), based on the preform reduction process (PRP), was investigated by means of XRD, SEM and this process, the mixture of TiO 2 powder and CaCl 2 was pressed into pieces as feed preform and was reduced by calcium vapor.
Okabe et al. in 2004 (Okabe et al., 2004) developed a preform reduction process (PRP) to produce titanium powder based on calciothermic reduction of preform containing TiO 2 by Ca vapor, and pure titanium powder with 99 mass% purity was obtained.
In 2004, a method for creating titanium powder through calcium vapour reduction of a T1O 2 preform was described in the Journal of Alloys and Compounds titled "Titanium powder production by preform reduction process (PRP
