A critical step in the researchers' protocol is reacting molten titanium with yttrium metal and yttrium trifluoride or a similar substance... A limitation of this work is that the resulting de-oxygenated titanium contains yttrium, up to 1% by mass; yttrium can influence the mechanical and chemical properties of titanium alloy. After solving the yttrium contamination problem, applications to industrial manufacturing will be straightforward. Any thoughts how they'll do that?
