T1 - Synthesis, Characterization and Electrical Properties of Both Pure and Cobalt-Doped Picromerite-Type Hydrated Double Salt K2Mg1−xCox(SO4)2·6H2O (x = 0, 0.4) LA - eng PY - 2016 SP - 4418 EP - 4424 T2 - Journal of Electronic Materials SN - 0361-5235 VL - 45 IS - 8 PB - Springer New York LLC AB - Polycrystalline samples of K2Mg1−xCox(SO4)2·6H2O (x = 0, 0.4) have been prepared by the slow evaporation method at room temperature. X-ray diffraction experiments confirmed the formation of pure crystalline picromerite. The electrical properties of the anhydrous compound K2Mg1−xCox(SO4)2 have been studied by means of complex impedance spectroscopy in the temperature range 340–420°C. The alternating current conductivity measurements exhibit features of the universal power law. Electric modulus properties of both pure and cobalt-doped picromerite have been investigated within a wide range of temperature and frequency.
