This is very cool indeed, but I laughed when I got to the conclusion:
> 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…
So the process removes the oxygen but then adds yttrium to the metal in significant amounts. That’s not quite the ultra pure titanium I was promised in the headline.
As always, I hope someone figures out the rest of the problem space. As-is, this looks like trading one problem for another.
