| Abstract Scope |
Low cost and high-quality titanium powder is crucial for powder metallurgy (PM) and additive manufacturing (AM) of titanium to significantly decrease the manufacturing cost. In this study, the production of titanium and titanium alloy powders from titanium sponge was studied through the shuttle of disproportionation reaction (Ti(II)→Ti(III)+Ti(powder)) and its backward reaction (Ti(III)+Ti(bulk)→Ti(II)) of Ti ions in molten salt. With the addition of a very small amount of TiCl<sub>2</sub>, over 7~70 times of titanium powder in mass comparing to the added titanium ion was obtained. Further, by introducing aluminium metal into the salt, fine Ti-Al powder with homogeneous composition and particle size distribution was obtained. The primary particle size of the powder formed was found approximately 1 μm, while the secondary agglomerated particle size was in the range of 25 ~ 50 μm. The proposed method is expected to significantly decrease the production cost of titanium and titanium alloy powders. |
