The kinetics of vaporization of SnO from silicate melts was studied in helium, nitrogen, argon and argon-helium mixtures, and in inert gas-carbon monoxide mixtures. The rate of extraction of tin from the melt via SnO vaporization was significantly higher in reducing gases than in inert gases. The enhanced vaporization phenomenon, commonly recognized in metallic systems, is demonstrated to occur in silicate melts. The vapor phase reduction of SnO (g) was studied experimentally, and the reduction was found to be very rapid. The addition of acidic or basic oxides to the binary SnO-SiO2 melts decreased the vaporization rate.
