Synthesis and StructureCharacterization of Germanate-Based Pharmacosiderites with Different Crystal Symmetries |
초록 |
The hydrothermal synthesisand crystal structuresof aluminogermanate and germanate analogs of pharmacosideritesin the cubic,orthorhombic and rhombohedral unit cells, as well as in the cubic body-centered superstructure are described. Under the synthesis conditions studied here, the crystal symmetry of the crystallized pharmacosiderite was found to differ according to the type and/or content of alkali cations employed. It is also shown that all four pharmacosiderites with different crystal symmetries undergo a two-phase transformation at elevated temperatures. |
