ACTIVITY MEASUREMENTS BY KNUDSEN CELL MASS-SPECTROMETRY - THE SYSTEM FE-CO-NI AND IMPLICATIONS FOR CONDENSATION PROCESSES IN THE SOLAR NEBULA
We report the use of new apparatus for the direct determination of the activities of components in minerals and melts by the measurement of their intrinsic vapour pressures at high temperatures using a Knudsen-cell mass spectrometer combination. The activity coefficients of Fe, Ni and Co have been d...
