Abstract
We report that the reaction of Nb with sapphire substrates at moderately high temperatures (≲1100 °C) is enhanced by mixing with Nb, a metal which has a higher oxygen affinity than Al. For example, the reaction of NbZr with Al2O3 at 950 °C results in the formation of zirconium oxide and Nb3Al with a superconducting Tc ≳17 K.Keywords
