Investigation of morphology and surface structure of small NaCl particles

  • M. Rösler
Condensed Matter


The morphology and the surface structure of small NaCl particles, produced by gasevaporation-technique (GET), were investigated by means of the decoration method. It was shown how the size and the morphology of the particles from the inner zone of the convection flow depend on the temperature of the evaporation source and the gas pressure. Details of the surface structure of spherical, facetted spherical and cubic particles are correlated with the experimental conditions of particle production. The first stage of sintering of cubic particles was detected from the step structure around the contact region. Evaporation structures on the particle surface were produced and described. The advantages of the decoration method in comparison with direct transmission of the particles were shown also for other NaCl aerosol generation methods.
