The complex dielectric response of cubic pyrochlore ceramics with the Bi1.5Zn1.0Nb1.5O7 composition was invetsigated between 100 Hz and 100 THz. The data obtained between 10 and 400 K revealed glss-like dielectric behaviour. The distribution of relaxation frquencies broadens on cooling and can described by a uniform distribution of relaxation frequencies.
