Abstract:

Structural characteristic and electrical properties of new type of perovskites with formula Ba x [Dy 0.25 Li 0.25 Be 0.50 ] 1-x TiO3 (0 < x <1) are prepared and investigated. The new perovskite Dy 0.25 Li 0.25 Be 0.50 TiO3. Crystallizes with orthorhombic distorted perovskite structure ,while Ba x [Dy0.25 Li 0.25 Be 0.50] 1-x TiO3 (0 < x <1) crystallizes with tetragonal distorted perovskite structure. Because of high melting points of oxides used here, samples are usually prepared by pressing and sintering powder. The anomaly in the relationship between electrical conductivity and dopant concentration in BaTiO3 is related to obstruction of grain growth during sintering. Above a certain dopant concentration the microstructure remains fine grained , thus resulting in the suppression of electrical conductivity due to existence of barrier layers. The concentration of Ba vacancies is added by the do pant concentration, and by the partial pressure of oxygen PTC type BaTiO3 ceramics were prepared and analyzed. The electrical properties of the composition in the series Ba x [Dy 0.25 Li 0.25 Be 0.50 ] 1-x TiO3 ( 0 < x <1) are reported. A probable mechanism for the conduction in these compounds bis also proposed.
