Electrical conductivity is an elegant experimental tool to probe the structural defects and internal purity of crystalline
solids. In the present study we have grown pure and KDP added DSHP single crystals by the slow evaporation method
from aqueous solutions at room temperature. Good quality transparent crystals have been obtained. Melting point and
density measurements were done. Electrical conductivity measurements were carried out with two frequencies, 100 Hz
and 1 kHz at various temperatures ranging from 2 to 30oC by using the parallel plate capacitor method. The present
study indicate that the dielectric constant and AC and DC conductivities increase with increase of temperature.
