“…Many tartrate compounds are formed by the reaction of tartaric acid with various positive ions and are used in numerous industrial applications for transducers and in linear and non-linear mechanical devices due to their excellent dielectric, ferroelectric, piezoelectric, and nonlinear optical properties (Abdel-Kader et al, 1991;Desai & Patel, 1988;Firdous et al, 2010;Torres et al, 2002). Several types of tartaric acid crystals, such as potassium hydrogen tartrate, KC 4 H 5 O 6 , and calcium tartrate, CaC 4 H 4 O 6 , develop naturally in bottled wine and are the major cause of wine's natural and harmless sediment (Boese & Heinemann, 1993;Buschmann & Luger, 1985;Derewenda, 2008;Hawthorne et al, 1982).…”

Differential scanning calorimetry, thermogravimetric-differential thermal analysis, and X-ray diffraction measurements were performed on single crystals of L(+)-tartaric, D(-)-tartaric, and monohydrate racemic (MDL-) tartaric acid. The exact crystal structures of the three acids, including the positions of all hydrogen atoms, were determined at room temperature. It was pointed out that one of O-H-O hydrogen bonds in MDL-tartaric acid has an asymmetric double-minimum potential well along the coordinate of proton motion. The weight losses due to thermal decomposition of L-and D-tartaric acid were observed to occur at 443.0 and 443.2 K, respectively, and at 306.1 and 480.6 K for MDL-tartaric acid. The weight losses for L-and D-tartaric acid during decomposition were probably caused by the evolution of 3H 2 O and 3CO gases. By considering proton transfer between two possible sites in the hydrogen bond, we concluded that the weight losses at 306.1 and 480.6 K for MDL-tartaric acid were caused by the evaporation of half the bound water molecules in the sample, and by the evaporation of the remaining water molecules and the evolution of 3H 2 O and 3CO gases, respectively.

“…Some crystals of this family are ferroelectric [1][2][3], some others are piezoelectric [4] and quite a few of them have been used for controlling laser emission [5]. As tartrates are sparingly soluble in water and decompose before melting, the gel method is found to be more promising than the high temperature crystal growth methods.…”

Pure and impurity (strontium) added calcium tartrate tetrahydrate single crystals were grown by the gel method. The FT-IR spectra of these crystals were recorded in the wavenumber range 400 -4000cm. The thermograms of the grown crystals were recorded in the temperature range 50 -900 o C. FT-IR spectra reveals the presence of water molecules, O-H bond, C-O and carbonyl C=O bonds. The thermograms show that these crystals are thermally unstable and decompose into its oxide through many stages. DTA curve of the pure crystal shows three endothermic and one exothermic peaks.

“…In a series of recent papers [16][17][18] we investigated the phase transitions in some organic and inorganic salts through the study of some of their electrical, thermal and/or calorimetric properties. Selected examples are: ammonium purpurate [16], ammonium tartrate [17] and mercury (II) and cerous (III) sulphates [18].…”

We report on some thermal properties (specific heat capacity G', thermal conductivity λ, and thermal diffusivity σ) in addition to the differential thermal analysis thermogram and thermogravimetric analysis for potassium hydrogen sulphate (KHS), KHSO4 . The accurate measurements of the above-mentioned parameters as functions of temperature revealed that the compound undergoes two structural phase transitions around 100°C and 175°C. It seems also likely that the compound behaves as a poorly conducting material and hence the maul mechanism of the heat transfer is due to p h o n o n s .
