Crystal chemistry, thermal expansion and dielectric properties of (Bi1.5Zn0.5)(Sb1.5Zn0.5)O7 pyrochlore

Cd and Mg replacement for Zn confirms that the Zn cation distributes between A and B sites in the BZS pyrochlore crystal structure. Thermal expansion of BZS pyrochlore was determined to be 7.92 × 10−6 K−1 between 20–650 °C while its dielectric properties showed a weak temperature dependence with dielectric constant of around 32 and dielectric loss of 0.005 at room temperature.
