They got about 50 degrees C, but note that the bulk sample and the more pure tiny sample are different. It definitely contributes to the general feel that however this works, it's an inefficient synthesis that's problematically generating the material we want. It certainly makes me wonder if something like molecular-beam epitaxy would be able to directly grow a more pure sample (but I imagine that's expensive and time-consuming to setup, plus not really what we're hoping for if we want to use lots of it).
