Superconducting, metallurgical and synthesis properties of Nb3Ga

A review is presented of the superconducting, metallurgical, and synthesis properties of Nb3Ga which are important for its potential application. The superconducting properties discussed are T/sub c/, H/sub c2/(T), and the dc critical current J/sub c/(H). Special metallurgical features of the Nb--Ga system which put severe constraints on synthesis techniques of potential practical importance for this material are discussed. Superconductivity data for materials synthesized by the techniques of quenching and annealing, chemical vapor deposition, and vacuum co-evaporation are reviewed. Recent results on the effects of radiation damage and its recovery by annealing are reviewed
