In a previous publication the order-disorder pyrochlore to fluorite transformation temperatures for a series of A(2)Hf(2)O(7) pyrochlores were predicted [C.R. Stanek and R.W. Grimes: Prediction of rare-earth A(2)Hf(2)O(7), pyrochlore phases. J. Am. Ceram. Soc. 2002, 85, p. 2139]. This was facilitated by establishing a relationship between these temperatures and the energy required to introduce a specific defect structure into the perfect pyrochlore lattice. Here an equivalent relationship for A(2)Zr(2)O(7) pyrochlores was generated, and from this the disorder temperatures for a number of compositions including Eu2Zr2O7 were predicted.
