摘要: Dielectric spectroscopy up to a frequency of 380 GHz has been performed on the molten salts fCasNO3d2g0.4fKNO3g0.6 (CKN) and fCasNO3d2g0.4fRbNO3g0.6 (CRN). For first time, conclusive results for transition region between a-relaxational far-infrared response have obtained in ionically conducting glass formers using dielectric spectroscopy. In addition loss, we present data reactive part constant. At high temperatures highest frequencies investigated, both materials exhibit sublinear spectrum. CRN loss follows power law with exponent 0.2 over three decades frequency. [S0031-9007(97)02888-3]
