Structrural peculiarities and some electrical-and-physical properties of bismuth oxide and antimony trichloride and tribromide

Abstract

The systems of antimony oxide (III) – antimony chloride (III), antimony oxide (III) – antimony bromide (III), bismuth oxide (III) – bismuth chloride (III) and bismuth oxide (III) – bismuth bromide (III) are the sections of the triple systems metal - oxygen - halogen. In the present report there is considered the information found in literature of the phase diagrams of binary systems components: metal – oxygen, metal – halogen – and literature data of methods of obtaining, structures and properties of the compounds in the systems. The analysis of the elementary cells parameters permitted to suppose their laminated structure and to build these compounds structures models. By the NQR method there was established the absence of the inversion center in some bismuth oxo-halogenides (by the presence of piezoelectric resonance lines) and revealed a significant dependence of NQR spectra transitions intensity on weak magnetic fields. From the practical point of view the interest presents further studying of crystal structures and physical properties of some bismuth oxo-halogenides, as due to the defect oxygen sublattice they can appear to be efficient solid electrolytes.
