Since the cuprates first appeared, a variety of other “high temperature” superconductors have been discovered – one is a simple compound of magnesium and boron, and another involves a mixture of iron and arsenic. Although none of them superconduct at temperatures as high as liquid air, they may ultimately be better materials with which to work.
在高温超导铜氧化物发现之后，科学界也发现了一系列其他类型的“高温”超导体——其中一种是镁和硼的简单化合物，另一种则是铁和砷的混合物。虽然这些材料都未能在高于气体液化温度的情况下实现超导，但他们可能会最终成为可供应用的更佳材料。考虑到不同元素间可以组合出成千上万种化合物，因此更好的超导材料很可能就在不远处。
