一、超导材料去年,日本科学家发现二硼化镁在零下234℃时成为超导材料,超过了此前金属化合物创下的超导温度。二硼化镁的优点是成本低廉,加工容易。美国科学家将氯仿和溴仿掺入C60分子,使C60分子的临界温度从零下221℃上升到了零下156℃。 First, superconducting materials Last year, Japanese scientists discovered that magnesium diboride became a superconducting material at minus 234°C, exceeding the superconducting temperature created by previous metal compounds. The advantages of magnesium diboride are low cost and easy processing. American scientists have incorporated chloroform and bromoform into C60 molecules, raising the critical temperature of C60 molecules from minus 221°C to minus 156°C.
