Abstract

Conditions for the growth of large and perfect single crystals of strontium tartrate trihydrate by controlled ionic diffusion of reacting ions through silica hydrogel have been optimized. The TGA/DTA thermograms reveal specific decomposition reactions. The values of several structural and physical parameters have been determined. The anisotropy in Vicker's microhardness leads to a study of fracture toughness, brittleness index and yield strength. The measurement of DC conductivity reveals hopping and band-type conduction mechanism with specific activation energy values in different temperature domains. Optical absorption study shows the existence of indirect transition at 5.20 eV and direct gap at 5.49 eV. The phonons invoked have been identified as internal vibration of strontium ions at 643 cm −1.
