Abstract: Simple bromides of copper and antimony are still in a focus of interest as compounds or products of decomposition of new complex halides for optoelectronics and photovoltaics. Here the interaction of copper(I) bromide and antimony(III) bromide are investigated on heating up to 650°C. No texturing effects are found for both simple bromides, the grains are shapeless and fused together. It has been demonstrated that SbBr₃ releases from the melt resulting in porous ceramic products with lack of antimony to copper. No new additional double bromides are observed in the binary system CuBr - SbBr₃.

Keywords: copper(I) bromide; indium(III) bromide; melt crystallisation; elemental composition; photoluminescence.
