Vaporization of the olivine sample containing 10 % fayalite was followed by means of mass spectrometric technique and using different Knudsen cells. The temperature dependence of partial pressures of the species identified in gaseous phase was established. The tensimetric values of the species were used to write the corresponding Clausius-Clapeyron equations. The comparison of the data obtained with the literature ones allows to draw some conditions about vaporization mechanism of the sample treated. |
