Abstract
A silicon clathrate compound of the following composition: EQU (Li.sub.4).sub.x Ae.sub.6 Si.sub.46 wherein (Li.sub.4) represents a Li.sub.4 cluster; Ae is an alkaline earth metal element selected from the group consisting of Ba, Sr and Ca; and x is the number ratio of the Li.sub.4 complex to the other elements and 0<x.ltoreq.2, which contains, as the structural units of crystals, Si.sub.46 clusters, each of which consists of Si.sub.20 clusters and Si.sub.24 clusters with cage structures formed by silicon atoms as the framework of the crystal and at least part of said Si.sub.24 clusters encapsulate alkaline earth metal atoms inside the cage, and at least part of the Si.sub.20 clusters encapsulate Li.sub.4 inside the cage.
