资源简介：
The clathrate-I phase Ba8−xSi46 (space group Pm3̅n) was synthesized by oxidation of Ba4Li2Si6 with gaseous HCl. Microcrystalline powders of the clathrate phase were obtained within a few minutes. The reaction temperature and the pressure of HCl were optimized to achieve good-quality crystalline products with a composition range of 1.3 x < 1.9. The new preparation route presented here provides an alternative to the high-pressure synthesis applied so far.
