摘要: Abstract Crystals of K2.51(NH4)1.49Hg3Cl10.2H2O undergo two phase transitions at T1=395 and T2=424 K. I—(395 K)→phase II—(424 III These have been detected by differential scanning calorimetry, impedance modulus spectroscopy techniques. The first transition T=395 K is related to NH4+ reorientation H+ diffusion. conductivity relaxation parameters associated with some K+/NH4+ conduction determined from an analysis the M″/M″ max spectra measured in a wide temperature range. Transport properties this material appear be due ions hopping mechanism.
