    Abstract

    The dielectric properties of single crystals and ceramics of BizV05 5 have been investigated as a function of pressure up to 4 GPa at room temperature.The dielectric constant and the loss are found to decrease with increase in pressure for all the samples under study. However. the rate of decrease of the dielectric constant in the case of partially grain oriented ceramic is higher than that of the single crystal and conventionally synthesised ceramic. The decrease in dielectric constant with increase in pressure is attributed to the decrease in ionic polarisation as a consequence of the decrease in interionic distances.
