Ferroelectric Aspect and Phase Transitions of Solid Solution of Cadmium Acetate with Aluminium (III) Oxide

The behavior of variation dielectric constant with temperature solid solution Cadmium Acetate Cd(C2H3O2)2 Aluminium (III) Oxide Al2O3 and other parameters have been measured between the temperatures 35°C to 100°C using capacitance bridge model ZENITH-FM89A Q meter at frequency 2000 Hz. In measurement, it observed that compound has lower value (ε = 1580) below 36ºC, which rises upto a 5600 moderate 45ºC. After this temperature, decreases nearly 3521 75ºC high peak 76°C 7000) in heating cycle curve some fluctuations.. When was studied cooling 62ºC(ε 6500), above intermediate fluctuations by increasing aluminium oxide content mother compound, its quality factor also increases little effect on constant. does not follow because relaxor behaviour compound. results explained basis crystal structure changes possibility free internal rotation acetate groups within lattice elevated temperature. One advantages is varying content, one can control coefficient resonant τf without affecting properties. This important for many ferroelectric applications near about low always required. A non-zero often preferable compensate due change resonator housing support structure. Solid suggests valuable as material excellent properties useful ceramics engineering communication system.
