Description
NH4+ (1 mol%) doped Nickel Sulphate Heptahydrate, NiSO4.7H2O crystals were grown by slow evaporation of aqueous solutions at room temperature. Starting materials of Ammonium Sulphate, (NH4)2SO4, NiSO4.7H2O salt powders and distilled-water were used to grow the crystals. Structural analysis of the crystal was investigated by XRD method. Temperature dependent electrical conductivity and dielectrics of the crystal were investigated in the temperature range of 300 K – 543 K by using PC-based temperature controller FOTEK MT-20 to study the high temperature phases and to determine the dehydration temperature (Tdehydration) of the crystal. TG-DTA method was used to formulate the high temperature phases and to conform the dehydration temperature of the sample.
