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.
我们报告说,通过与 Nb 混合,Nb 与蓝宝石衬底在中等高温(≲ 1100 °C)下的反应会增强,Nb 是一种比 Al 具有更高氧亲和力的金属。例如,NbZr 与 Al2O3 在 950 °C 的反应导致形成氧化锆和 Nb3Al,其超导 Tc ≳17 K。
