Samenvatting

Knudsen effusion mass spectrometry and a static method were used to study the vapor composition 'and the thermodynamic properties of the Si-P melt with the phosphorous content from 0.09 to 26.5 at. % in the temperature range 1507 to ~8~1 K. A representatIve file of experimental data comprising about 100 values of phosphorus activiIty at vanous concentrations and/or temperatu!es was obtained. The thermodynamic characteristics as functions of temperature and concentration were approximated by the ideal associated-solultion model uder the assumption that SiP and Si2P complexes exist in the melt. The boundanes of the region of liquid phase stability on the phase diagram were computed, and agreement with the available expemnental information was obtained.
