TABLE 3.

The T _O−D in K computed with different methods: modeling disordered phase by defect fluorite (PY-DF), weberite (PY-WB) and defect fluorite/weberite mixture by the two state model of Finkeldei et al. (2017) (PY-WB/DF), and measured for selected pyrochlore compounds. In parentheses we provide the estimated configurational entropy of disordered phase in J/K/mol.
