Abstract

Experimental results concerning the nucleation of supersaturated glycerol vapors in the atmosphere of sulfur hexafluoride near the melting point of the condensate were obtained in a flow-type diffusion chamber. The nucleation process appeared to be affected by the phase transition in the condensate. The melting point of the condensate was found to shift with increasing concentration or pressure of the carrier gas in a way that is typical of binary systems. The effect of the carrier gas pressure on the rate of aerosol formation was established. The results confirm the assumption that molecules of a noncondensing (under the conditions of the experiment) gas participate in the formation of critical nuclei; thus, the process in question should be interpreted as binary nucleation.
