METHOD OF MAKING SILICON CLATHRATES |
| 摘要 |
A method of preparing a substantially homogenous, alkali-metal silicon clathrate composition containing the silicon clathrate MxSi136 (3 </= x </= 24). The silicon clathrate is prepared by rapidly heating an alkali-metal silicide under a high vacuum to a decomposition temperature of at least 365 DEG C. The produced silicon clathrates are in a substantially homogenous MxSi136 phase with only small amounts of a metallic silicon clathrate phase, MySi46. A method of reducing the alkali-metal content of a silicon clathrate MxSi136 (x > 0) is also provided.
