The goal of the paper is the synthesis and study of the properties of compounds in the system HfO/sub 2/ (ZrO2)-SrO(BaO). These compounds form in the region of high alkaline-earth content. The phase composition of the samples was studied by x-ray and petrographic analyses on a DRON-1.5 unit at room temperature. It was established from the studies that, independent of the means of sample preparation, there form on interaction of the dioxides of hafnium and zirconium with the oxides of strontium in the region of high SrO content the compounds Sr/sub 4/HF/sub 3/O/sub 10/, Sr/sub 4/Zr/sub 3/O/sub 10/, Sr/sub 3/Hf/sub 2/O/sub 7/, Sr/sub 3/Zr/sub 2/O/sub 7/, Sr/sub 2/HfO/sub 4/, and Sr/sub 2/ZrO/sub 4/. The unit-cell parameters and crystal-optical characteristics of the compounds synthesized were determined.
