添加钛的多芯Nb_3Sn超导体在日本已具工业生产规模。几个15T级的(Nb、Ti)_3Sn超导磁体已建造成功,在日本并投入运行。近来,一种新的场强可达18T以上的超导体,也已经用多芯(Nb、Ti)_3Sn建造,并改善了V_3Ga超导体,关于新的超导体的发展,一种连续液体快冷和高能量束辐照技术正在研究用来合成Nb_3Al和它们的三元化合物。化学气相沉积制造Nb3_Ge带已成为一种较为可靠的方法。溅射方法对合成高超导电性能的NbN是有效的。在超流液氮温度下,具有优异的高场性能的V_2(Hf、Zr)已制成多芯线。气相扩散和粉末冶金方法在制造PbMo_6S_3方面也得到进展。
Titanium-doped multi-core Nb_3Sn superconductor in Japan has been the scale of industrial production. Several 15T grade (Nb, Ti) _3Sn superconducting magnets have been successfully constructed and put into operation in Japan. Recently, a new superconductor with field strength up to 18T has also been constructed with multi-core (Nb, Ti) _3Sn and improved V_3Ga superconductor. With regard to the development of new superconductors, a continuous liquid quench and high energy Beam irradiation technology is being investigated for the synthesis of Nb 3 Al and their ternary compounds. Chemical vapor deposition of Nb3_Ge belt has become a more reliable method. The sputtering method is effective for synthesizing NbN with high superconductivity. V_2 (Hf, Zr) with excellent high field performance has been made into multi-core wire at superfluid liquid nitrogen temperature. Vapor phase diffusion and powder metallurgy methods have also progressed in the fabrication of PbMo_6S_3.
