用蒸发技术研究了铯原子在液相区（1230 ~ 1310 K）的蒸发行为。对冷凝物和残留物的化学和X射线衍射分析证实蒸发是一致的。假设物质是单体，计算蒸汽压，并可通过以下公式给出：log p（kPa）=（6.37±0.29）-11452±370）T（K）。数据已被用来推导相关的热力学量。
The vaporisation behavior of caesium molybdate has been investigated in the liquid region (1230 to 1310 K) by a transpiration technique using dry oxygen as the carrier gas. Chemical and X-ray diffraction analysis of the condensate as well as the residue confirmed the vaporisation to be congruent. Assuming the species to be monomeric, the vapour pressures were calculated and can be given by the following equation: log p (kPa)=(6.37±0.29)− 11452±370) T (K). The data has been used to derive the related thermodynamic quantities.
