Single crystals of pure and mercuric (II) chloride doped KDP have been grown by slow evaporation method. Dielectric constant and dielectric loss have been obtained as a function of frequency between 1 KHz and 5 MHz and temperature range between 353 K and 403 K. The dependence of tan δ, ε and σac on temperature and frequency of the applied field (50 Hz-5 MHz) is established. Both dielectric constant and dielectric loss decreases with increase in frequency. Impedance plot has also been drawn at four different temperature and results are discussed in the paper.
