Three compounds: ErGe_2, Er_2Ge_3 and ErGe were observed in this region. A eutectic reaction composed of 23 at.-％ Er occurs at 866℃. ErGe_2 and Er_2Ge_3 are formed by two peritectic reactions at 900 and 1043℃ respectively. DTA indicated that ErGe_2 undergoes a polymorphic transformation at 886℃. There is no detectable solubility of Er in Ge. 收稿日期: 1983-04-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 李国运 郑建宣 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I4/127 1 Schmidt, F.
