X-ray single-crystal diffraction study of pyrope in the temperature range 30-973 K

The behavior of synthetic pyrope garnet molecules under a range of temperatures was studied using x-ray spectroscopy. Choice of the temperature range of 30-973 degrees kelvin, makes way for a detailed geometrical analysis of the polyhedral distortions in this range, the determination of the thermal expansion for bond distances, and the measurement of the atomic displacement parameters. Applications of various tensors used for analysing thermal effects are discussed.
