Mass Spectrometric Investigations of the Evaporation of Crystalline Compounds of the System Cs
نویسنده
چکیده
The evaporation of the synthetic compounds CsAlSi04 and C s A l S i s O i 2 was studied by high temperature mass spectrometry. The measurements were carried out under equilibrium conditions with Knudsen cells in the temperature ranges 1242 to 1567 K (CsAlSiC>4) and 1542 to 1803 K (CsAlSi50i2). The obtained Cs partial pressures are given by the equations log p (Pa) = 18 497/T (K) + 11.85 (CsAlSi04) and log p (Pa) = 26 974/T (K) + 14.6 (CsAlSi50i2) .
