    Processes of Formation of Micro- and Nanodispersed Systems is a comprehensive analysis and presentation of the physical processes and phenomena that lead to the formation of disperse materials. It also details the properties of disperse materials yielded from various processes.



    Special attention is given to the homogeneous condensation of metal vapours from expanding metal vapours in a vacuum, as well as heterogeneous condensation of metal vapours on solid substrates in the presence of impurities during the formation of disperse condensates. The book also examines flow in thin films, the decay of thin films, and phenomena accompanying the coalescence of disperse particles.



    Using currently available data, this book compares different methods of producing disperse materials in terms of scale. It also describes several applications of the experimental results it presents, including:





    • Production of composites of nanodisperse metals in an organic matrix


    • Production of metallic powders


    • The potential to produce metallic powders on an industrial scale with the creation of a special plant


    • Fine cleaning of gases contaminated with micro- and nanoparticles, including aerosols such as spray paint


    Covering and expanding applications of key processes concerning metal vapours, Processes of Formation of Micro- and Nanodispersed Systems is highly valuable to researchers of semiconductors. It provides a single source of detailed and practical information on the processes and phenomena related to the formation of disperse materials. It represents the current state of research and practice in micro- and nanodispersed systems while highlighting paths to advancement in the field.
