超导化合物一般不便于塑性加工,因此,研究线材制造工艺将是解决超导化合物能否商品化的关键。为促进这个领域的发展,研究了几种线材制造的方法。 V_3Ca或Nb_3Sn的制备是首先设法将镓或锡连续扩散在钒或铌的基带表面,然而用常规的扩散方法形成V_3Ga是困难的,而添加铜作为镓的催化剂对V_3Ga的生成是有效的,并且成功地制成了V_3Ga线。利用V_3Ga带制成的超导磁体能产生世界上最 Superconducting compounds generally do not facilitate plastic processing, therefore, the study of wire manufacturing process will be the key to solve the commercialization of superconducting compounds. In order to promote the development in this field, several methods for manufacturing wire materials have been studied. The preparation of V_3Ca or Nb_3Sn first tries to diffuse gallium or tin continuously on the surface of a base of vanadium or niobium. However, it is difficult to form V_3Ga by a conventional diffusion method, whereas adding copper as a gallium catalyst is effective for the generation of V_3Ga, and Successfully made V_3Ga line. Superconducting magnets made of V_3Ga can produce the most in the world
