Investigations of Homogeneous Nucleation in Fe, Si, Fe/Si, FeO(x), and SiO(x) Vapors and Their Subsequent Condensation,

Abstract

Critical pressures vs temperatures for avalanche condensation of homogeneously nucleated Fe, Si, Fe/Si, FeOx and SiOx vapors are reported. In homogeneous cluster formation rates were obtained. Mixtures of 0.1 to 2.5% Fe(CO)5 and/or SiH4 in Ar, N2O/Ar or H2/N2O/Ar were heated behind reflected shocks to temperatures above the boiling point of the condensed phase. Condensation which occurred in the subsequent expansion fan was monitored by light scattering and turbidity of the sample.
