The recent report that Nb$sub 3$Ge films can be prepared with superconducting transition temperatures of over 22K has immediately made Nb$sub 3$Ge a very important potential candidate for a variety of large scale applications, such as for example, power transmission lines, or large high field magnets. Short sample data on sputtered films show that Nb$sub 3$Ge possesses an extremely attractive combination of high field properties, competitive with any other presently known material at all temperatures from zero to T/sub c/. The development of a process capable of being used to fabricate Nb$sub 3$Ge in a useful configuration (i.e., long length of wire or tape) is now being investigated. Chemical vapor deposition (CVD) is a demonstrated commercial process, which may be applicable for this purpose. Initial CVD studies have yielded films with T/sub c/'s over 21.5$sup 0$K. (auth)
