摘要
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 x 10(-6) K-1 between 20-650 degrees 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.
