摘要：

The surface tension and the density of Si-B alloys with a boron content of 22.4 at.% were studied in a helium atmosphere in the temperature range 1410 - 1700 °C. We calculated the activity coefficients of the component in the melt and the composition of the surface layer. We investigated the enthalpies of the mixing of liquid Si-22.4 at.% B alloys at 1813 K. The oxidation kinetics of liquid Si-B alloys with boron contents of 1.28, 12.02 and 22.4 at.% was investigated at temperatures of 1450, 1500 and 1550 °C. The effect of temperature and of boron concentration on the oxidation rate of the liquid phase was studied. © 1979.
