Аннотация:
The behavior of aerosols formed over boiling melts of substances (boiling temperature 500-1800 K) in a stream of a carrier gas at 300 K was studied. Microparticles of size from 0.2 to 10 Ојm, partially aggregated, were detected in the aerosol. In an applied electric field with an intensity of 150-1000 V cm -1, the particles migrated toward the negatively charged electrode at a velocity of 5-15 cm s -1. The velocity of their motion was a linear function of the field intensity and depended on the melt boiling temperature in accordance with the Arrhenius equation. Experimental data were interpreted on the basis of a concept that, in the course of the growth of each microparticle, vapor molecules adsorbed by it decompose into ions with nonequivalent transfer of cations and anions into the particle volume, i.e., the microparticles undergo growth charging at the activation energy of the cation release from the particle surface into vapor of approximately 0.5 eV. © 2011 Pleiades Publishing, Ltd.
