本文用克努森扩散和质谱技术研究了稀土氧化物La_（20）_3和Nd_（20）_3在高温下的蒸发。两者几乎化学计量地蒸发成一氧化碳和氧气。生成热，<，单位为kcal。mole ~（-1），离解能D_o分别为：LaO，-29.8±4，8.08±0.2，NdO，-30.0±6，7.18±0.3。
The vaporization of the rare earth oxides, La203 and Nd203, at elevated temperatures has been studiedby a combination of Knudsen effusion and mass spectrometric techniques. Both vaporize almost stoichiometrically to the monoxide and oxygen. The heats of formation,<, in kcal. mole-1, and dissociation energies, Do0, in ev are: LaO,—29.8±4, 8.08±0.2; NdO,—30.0±6, 7.18±0.3, respectively.
