Dielectric properties were studied on fourteen langbeinite-type crystals. Measure-ments were performed in the temperature range 20 - - 196'C for single or polycrystal-line samples. It was newly f'ound that five crystals undergo phase transitions;(NH.).Mg.(SO.). at - 52'C, (NH.).Ni.(SO.). at - 113'C, K.Co.(SO.). at - 147'C,(NH.),Ca.(SO.). at -115'C and Rb.Ca.(SO.). at -90'C. A tentative discussion ismade to classify the bahaviors of phase transitions in langbeinite family in respect to thelattice constants and ionic radii of constituent tons.
