Abstract

ABSTRACT: The synthesis of (1- x )Na0.5 Bi0.5 TiO3 -xBa0.66 Mg0.04 Sr0.3 Sn0.1 Ti0.9 O3 by the wet solid-phase method was successfully investigated. The microstructure, dielectric properties, and temperature stability of the obtained ceramics were investigated in detail. The size of the grains was determined by scanning electron microscopy. It was determined that the addition of Na0.5 Bi0.5 TiO3 could enhance the dielectric constant. When the NBT amount is 0.4 mol%, the dielectric loss of capacitance is below 0.11 and the dielectric constant of the composites is about 1720. The temperature coefficient of capacity varied from −12.24% to 4.79% at the temperature range between −55°C and 200°C. The temperature-capacitance characteristics meet EIA X9R specifications.
