The composites based on superionic (Cu₁₋xAgx)₆PS₅I solid solutions were prepared by mixing of microcrystalline powder with polyvinylacetate glue. The temperature and frequency behaviour of the total electric conductivity ...

Cu₆(P₁₋xAsx)S₅I mixed crystals were grown using chemical vapour transport. Temperature isoabsorption investigations of optical absorption edge enable to reveal anomalies typical for the first- and second-order phase ...
