| 摘 要： | 本文用X射线粉末法测定了FeGa3的晶体结构,FeGa3属四方晶系。在20℃的点阵常数是:a=6.2628?,c=6.5559?。每晶胞包含四个化合式量。空间羣为D4h14——P42/mnm。Fe原子占据在4(f)等效位置上,Ga原子占据在4(c)及8(j)等效位置上;参数为:xf=0.343,xj=0.157,zj=0.264。从结构看来,这是金属互化物的一种新类型。

| Abstract: | The crystal structure of FeGa3 has been determined by means of Debye-Scherrer photographs. The unit cell is tetragonal, with a = 6.2628? and c = 6.5559? at 20℃. There are four formula units per unit cell. The space group is D4h14——P42/mnm. The four Fe atoms are situated at the 4(f) positions, while the twelve Ga atoms are situated at the 4(c) and 8(j) positions, the atomic parameters being xf=0.343,xj=0.157 and zj=0.264.This structure represents a new type of intermetallic compound. |
