Thermal Analysis Studies of the Decomposition of Hydrated and Deuterated Rochelle Salts
Abstract
Rochelle Salt is the common name given to the double tartrate of sodium and potassium, which crystallizes as the tetra- hydrate. The important dielectric and ferroelectric properties of hydrated and deuterated Rochelle Salts have been well documented (1,2,3). These materials are important commercially for their piezoelectric properties as acoustic transducers. Although there have been many reported investigations of the physical properties of Rochelle Salts, the thermal decomposition has not been investigated above 60 °C.. It is the purpose of this paper to report studies of the thermal decomposition of single crystals of these salts by the thermal analytical techniques: Differential Scanning Calorimetry (DSC) andThermogravimetry (TGA).
