제목 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.
