Abstract
A V3Ga or Nb3Ga superconducting intermetallic compound is produced on a support of V or Nb by bringing a gaseous Ga alkyl compound into contact with the support and heating it to the decomposition temperature, e.g. 200-500 DEG C. for 1/2 -1 minute under a vacuum of 1-10-2mm Hg, to deposit a Ga layer, and then heating the support e.g. for 1 to 10 minutes under vacuum or in a protective gas e.g. A or He to diffuse the Ga into the support and react therewith. The heating may be effected at 900-1200 DEG C. for V and 1200-1500 DEG C. for Nb. The alkyl compound may be Ga triethyl, triisobutyl, tri-n-hexyl or Ga diethyl hydride. The support may be in the form of wire, ribbon, plate or cylinder, and may be heated inside a quartz reaction tube by resistance, radiation or induction heating.ALSO:A V3Ga or Nb3Ga superconducting intermetallic compound is produced on a support of V or Nb by bringing a gaseous Ga alkyl compound into contact with the support and heating it to the decomposition temperature, e.g. 200-500 DEG C. for 1/2 -1 minute under a vacuum of 1-10-2 mm.
