一、引言 对碱金属和镓形成的合金的第一批研究工作,要追溯到几十年以前。碱金属的活泼性给合成技术和结构的测试技术提出了苛刻的要求,所以,这方面的研究工作,一直进展不快。 第一次用热化学相图的方法来研究这类化合物的是Feschotte。稍晚是Klemm,最近有Yatsenko等,他们都曾系统地研究过这类化合物。但是,他们的研究结果相互之间差异甚大。 I. INTRODUCTION The first research work on alloys formed from alkali metals and gallium dates back several decades. The liveliness of alkali metals poses harsh requirements for the testing of synthetic and structural technologies, so research in this area has been slow to progress. Feschotte was the first to study this class of compounds using the thermochemical phase diagram method. Later Klemm, and recently Yatsenko et al., Who have systematically studied such compounds. However, their findings vary greatly from each other.
