摘要
本文研究了 SrO—CuO 和 Bi_2O_3-CuO 两个二元系的相关系,测定并绘出了这两个系统的相图。得到了一些新结果。
The phase relationships of SrO-CuO and Bi_2O_3-CuO systems were determined.In the SrO-CuO system,there exist three incongruent compounds with the mole ra-tios of SrO:CuO,2∶1,1∶1 and 7∶12.The lattice parameters of 1∶1 and 7∶12compounds were measured by XRD to have the results:SrO·CuO,tetragonal witha=11.5528(6)(?),c=14.0968(9)(?);7SrO·12 CUO,orthorhombic with a=11.474(1)(?),b=9.183(1)(?) and c=6.6954(9)(?).For the Bi_2O_3-CuO system,only oneincongruent compound Bi_2O_3·CuO(1∶1,not 2∶1)was detected.The phase diagramsof SrO-CuO and Bi_2O_3-CuO systems are presented.
