Superconductor prodn. by chemical vapour phase deposition on fibre - by exposing niobium or tantalum to nucleating gas and nucleating agent to give uniform film

Superconductor prodn. involves deposition of a uniform Ta and/or Nb (cpd) film on a fibrous support by chemical vapour phase reaction. The fibres with Ta/Nb are exposed to N2 gas or a gaseous N cpd. and a H halide, so that the H halide reacts with Ta/Nb to form a gaseous cpd. which then reacts with...
