Abstract : A study of the condensation of metal vapor in an inert carrier gas was made with primary emphasis on the size of the particles formed and the location of the onset of the condensation. Superheated zinc vapor was generated in a hotshot wind tunnel in a helium carrier gas and expanded in a converging-diverging nozzle. Static pressure measurements were made to determine the location of the onset of condensation. A sampling method was developed and used to determine the size of the condensed particles. An exploding wire arrangement was also used in a few additional studies and condensed platinum and other metal particles were obtained. A few measurements were also made of the condensation of argon.
