Hydrothermal growth and morphology of calcite single crystals

摘要

In this paper, an experimental study is reported for the hydrothermal growth of calcite single crystals, CaCO_3, using the seeds parallel to pinacoid (0 0 0 1). Morphological stability of the most important faces is considered, and the real structure of these crystals was studied by X-ray topography. Physical properties of the crystals grown are similar to the rhombohedral (1 0 1 1) ones, but they have higher optical homogeneity.
