日本真空冶金公司自1991年7月出售C_60、C_70以来,订货合同已达100余份。自美国AT&T公司贝尔研究所及日本电气公司在日本金沢召开的第三届国际超导会议上发表研究论文以来,继金属系、氧化物系之后,成为第三高温超导材料,引起有关方面注意,并积极开展研究工作。 C_60是集聚了60个碳原子的吸盘状分子,为直径7的微小中空球体,球体中间可放入一个金属 Japan Vacuum Metallurgical Company sold C_60 since July 1991, C_70, the contract has reached more than 100 copies. Since the United States AT & T Bell Institute and NEC held a research paper at the third session of the International Superconductivity Conference held in Kimcheon, Japan, following the Department of the metal, the Department of oxide, became the third high temperature superconducting material, causing the attention , And actively carry out research work. C_60 is a collection of 60 carbon atoms of the sucker-like molecules, the diameter of 7 tiny hollow spheres, the ball can be placed in the middle of a metal
