Abstract
Sr0.9775Sm0.015TiO3 ceramics with giant permittivity of about 40,000 and low dielectric loss of 0.0068 measured at 25 °C and 1 kHz were obtained by sintering the ceramics in N2 at 1500 °C. The surface structure was analyzed by XPS measurement, which implied that a large number of Ti3+ ions existed in the Sr0.9775Sm0.015TiO3 ceramics sintered in N2. The results indicated that making the oxygen vacancies fully ionized by N2 sintering could increase the permittivity and decrease the dielectric loss effectively.
