Vapour pressure measurements on Nd–Te system

Vapour pressure measurements on Nd–Te system

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...

Zusammenfassung: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 NdTe 2 phase has been precisely determined under experimental conditions reported. Graphical abstract
