What's very cool is that the recipe in the paper is trivial. It's just lead, phosphorus, and copper, fired in a kiln under a vacuum. With a couple hundred dollars of equipment, one could even attempt to make this at home (wouldn't recommend with the powdered lead tho).
So if the claim holds up true, mass producing it should be quick.
That said, the lead makes this material not fit for use for a lot of applications due to its toxicity.
