suggesting that there is little dissolution or exsolution of different constituents over the observed temperature range. Furthermore, we compared the position and shape of the peaks from segregated CaTiO3 in calcined BCZT to the diffractogram of pure CaTiO3 synthesized at the same conditions (Figure ) -the good fit confirmed that CaTiO3 only accommodates a negligible fraction of other elements, which is consistent with literature and supports the conclusion drawn from the lattice parameters (Figure ).
