自从瑞士的Bednorz和Mller于1986年发现La—Ba—Cu—O陶瓷的超导电性以来,在世界范围内,许多学者先继对高温超导材料进行了研制,这种研制工作目前集中在三个系列上:含稀土氧化物系列、铋锶钙铜氧化物系列和其它氧化物系列.我们已对含稀土氧化物系列和铋锶钙铜氧化物进行了研制.
Since the discovery of the superconductivity of La-Ba-Cu-O ceramics by Bednorz and Mller in Switzerland in 1986, many scholars have successively developed high-temperature superconducting materials all over the world. At present, the research work is focused on three A series of: containing rare earth oxide series, bismuth strontium calcium and copper oxide series and other oxide series.We have rare earth oxide series and bismuth strontium calcium copper oxide has been developed.
