Abstract
Although particles of metals and metallic derivatives in the form of fume have been a widespread source of industrial wastage and pollution, aerosol generation is useful in the production of fine powders where features of the particles such as shape and surface texture are important. Methods of aerosol formation by dispersion and by condensation are surveyed, and the physical properties of the particles described. Tables of particle characteristics are given for pure metals and alloys. A notable feature of condensation aerosols, intensively studied in recent years, is the variety of shapes and structures that can occur, depending on the pressure and temperature conditions maintained in the generating plant. Progress towards the understanding of the mechanisms responsible for the various types of particle has been made, and attention is drawn to the potential usefulness of the new knowledge in powder manufacture and fume abatement.
