Non Linear Dielectric Phenomenon in BaTiO3 - Bi (Ti1-xMgx)O3 . Ceramic Material

The distinguishing characteristic of an insulator is its resistivity. An has a higher resistivity than semiconductor or conductor and high dielectric properties. adjustable property characterized by change in the permittivity under applied electric field, this phenomenon called "dielectric nonlinearity" (dielectric tunability properties). With these properties, new will arise properties ceramic materials. aim research to observe non-linear BaTiO3-Bi(Ti1-xMgx)O3 material with x= 0.5, 0.6, 0.7, 0.8 0.9. Ceramic materials were synthesized using sol-gel method which produced nano-sized powders. Impedance data was measured impedance analyzer (Solartron SI 1260, Solartron Metrology, West Sussex, UK) frequency range 100 Hz 500 ac measuring voltage 0.1 V. Dielectric from 0oC 250oC automatic component analyzer. at 10 kHz. All samples show different maximum permittivity. highest obtained 0.6 but transition temperature where phenomena occurred found sample 0.5.
