On the growth of calcium tartrate tetrahydrate single crystals
X. Sahaya Shajan,C.K. Mahadevan +1 more
TL;DR: In this paper, the role played by formate-formic acid on the growth of crystals is discussed, and the grown crystals were characterized by atomic absorption spectroscopy (AAS), X-ray diffraction analysis (XRD), microhardness measurement, Fourier transform infrared spectrograph (FTIR), thermogravimetry (TG), and differential thermal analysis (DTA).

Dielectric and thermal studies on gel grown strontium tartrate pentahydrate crystals
TL;DR: In this paper, the results of dielectric and thermal studies on strontium tartrate pentahydrate (STP) crystals are described, and it is explained that crystallographic change due to polymorphic phase transition may be occurring in the material, besides the change resulting from loss of water molecules, which leads to the dielectrics anomaly at around 100°C.
