Differential Thermal Analysis and Dielectric Studies on Neopentanol under Pressure
Differential thermal analysis (DTA) and dielectric measurements have been performed on 2,2-dimethyl-l-propanol (neopentanol) up to 200 MPa. Neopentanol exhibits at least one orientationally disordered (ODIC) phase (solid I) that transforms at lower temperatures to a non-plastic phase (solid II). There is evidence of a further O D I C phase denoted as solid I'. The pressure dependence of the pha...

15 صفحه اولRaman scattering and lattice-dynamical calculations of crystalline KNO3.
The Raman spectrum of a KNO3 single crystal was measured at both room and liquid-nitrogen temperatures. Lattice-dynamical calculations, based on the rigid-ion approximation and empirical potentials, were performed. The possibility of a phase transition at 217 K was investigated by measuring the temperature dependence of the Raman spectrum. ©1992 The American Physical Society. Used by permission...
متن کاملDielectric and ultrasonic studies of new Ag0.1Cu0.9InP2S6 layered ferroelectric compound
The dielectric properties of newly synthesized Ag0.1Cu0.9InP2S6 crystals were investigated in broad frequency (20 Hz – 1 MHz) and temperature range (110 K – 350 K). Anomaly in the temperature dependence of a complex dielectric permittivity indicating the polar phase transition was detected at the temperature 283 K . The dielectric properties of the presented crystal are mainly caused by conduct...
متن کامل“Thermal Stabilization Effect” of Al2O3 nano-dopants improves the high-temperature dielectric performance of polyimide
Insulation performance of the dielectrics under extreme conditions always attracts widespread attention in electrical and electronic field. How to improve the high-temperature dielectric properties of insulation materials is one of the key issues in insulation system design of electrical devices. This paper studies the temperature-dependent corona resistance of polyimide (PI)/Al2O3 nanocomposit...
