Hydride-Dehydride (HDH) Process
The Hydride-Dehydride process involves the conversion of titanium sponge or scrap into a hydride form. This hydride is then subjected to a dehydrogenation process, resulting in the production of titanium powders. The HDH process offers good control over particle size, purity, and morphology.
Armstrong Process
The Armstrong process utilizes the reaction between titanium tetrachloride and magnesium to produce titanium powders. In this method, the titanium tetrachloride is reduced by magnesium in a high-temperature reactor, leading to the formation of titanium powders. The Armstrong process is known for its efficiency and ability to produce high-purity titanium powders.
Plasma Atomization
Plasma atomization involves the use of a plasma torch to melt a titanium feedstock. The molten titanium is then atomized into fine droplets using high-velocity gas. These droplets solidify into titanium powders upon contact with a cooling medium. Plasma atomization offers control over particle size distribution and the production of spherical particles.
