ABSTRACT
In the 1990’s the authors developed an experimental technology to produce various nanosized metal-organic composites [1] with unique properties [2] by joint vacuum deposition of two components of the vapours on a cryogenic condenser. During the experiments, the authors were surprised by two circumstances. First, the inability to provide long-term stable operation of the process without manual adjustment. Second, even when applying a mixture of vapours with a low content of metal vapour in comparison with the vapour of organic matter the final product turned out to have a high concentration of the metal [3]. These two circumstances have not found a sufficient understanding and radical solutions. Therefore, in order to revive work on nanodispersed composites the authors carried out mathematical modelling of the condensation of two-component vapour on the cryogenic surface. The condensation of water and silver vapours on the surface with a temperature of 223 K was modelled. The calculations showed a number of new and unexpected phenomena that help explain the strange behaviour of processes in the experiments and develop a technology of production of composites on a new level.
