Abstract
Li1−x H x IO3 solid solutions have been obtained for several values of the concentration x. The crystalline samples have been analyzed by Raman spectroscopy and dielectric techniques. The polarized Raman spectra reveal an average hexagonal symmetry for the disordered solid solutions formed for x between 0.22 and 0.36. The dielectric constants and the AC resistivities show a low anisotropic character for the ionic conduction in the disordered sample, as compared with the pure α–LiIO3 crystal.
