《Pyroelectric properties of the triglycine sulphate crystal formerly influenced by a transverse electric field》 was written by Fugiel, Boguslaw; Kikuta, Toshio. Product Details of 6381-59-5This research focused ontriglycine sulfate rochelle salt pyroelectricity elec field hysteresis polarization. The article conveys some information:
Measurements of the hysteresis loop and pyroelec. c.d. have been carried out. It has been shown that the function describing the remanent polarization decay over time generated by a prolonged transverse elec. field is for TGS qual. the same as for other uniaxial ferroelecs. (TGSe, Rochelle salt) regardless of the fact that different electrode-sample systems were used. A prolonged application of an elec. potential Vs at temperature T = TA < TC (TC is the critical temperature of the paraelec.-ferroelec. phase transition) to a side ring electrode of a round plate sample changes pyroelec. properties of TGS and leads to the memory effect. For T < TA, the polarization P values obtained by time integration of elec. c.d. measured after Vs disconnection differ from those measured before Vs application by a constant value, and therefore, the first derivative ∂P/∂T remains unchanged provided that the temperature TA is not exceeded. In the experiment, the researchers used Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Product Details of 6381-59-5)
Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5) is a ferroelectric crystal with a high piezoelectric effect and electromechanical coupling coefficient. Product Details of 6381-59-5 It may be used as a constituent to prepare DNS (3,5- dinitrosalicylic acid) reagent and Fehling′s solution B, which are used in the determination of reducing sugar.
