Abstract
The vaporization behavior of cesium molybdate (Cs2MoO4) has been studi ed by using the Knudsen effusion mass spectrometry. A combination of a molybdenum outer cell and an alumina inner Knudsen cell was utilized in the Nuclide 12-90 HT high temperature mass spectrometer. The obtain ed vapor pressure P(Pa) of Cs2MoO4(g) is as follows: log P = - 1.21 X 10(4)/T + 9.80 for temperatures higher than the melting point of CS2Mo O4, 1229.5 K, and, log P = - 1.36 X 10(4) T + 11.02 for temperatures l ower than 1229.5 K, where T is in K.
