摘要
采用非等温等压法对钕碲样品进行了平衡蒸气压测量。样品在 821 至 1100 K 的温度范围内进行了平衡。利用在 ~ 64.0-74.5 at% Te 成分范围内获得的蒸汽压力数据，确定了 Te 的热力学活性。在报告的实验条件下，精确测定了 NdTe2 相中的非化学计量。
Equilibrium vapour pressure measurements were carried out over the neodymium–tellurium samples using the non-isothermal isopiestic method. The samples were equilibrated in the temperature range from 821 to 1100 K. Using vapour pressure data obtained for the composition range ~ 64.0–74.5 at% Te, the thermodynamic activities of Te were determined. Non-stoichiometry in the NdTe2 phase has been precisely determined under experimental conditions reported.
