  • Abstract
    The specimens of (Ba1-xCax)TiO3 [x=0, 0.1, 0.2, 0.3, 0.4, 0.5] were fabricated by a solid-state reaction method, and their humidity-sensitive characteristics were examined. Ca inhibits grain growth and the open porosity increases with Ca substitution, and the specimen of (Ba0.5Ca0.5)TiO 3 exhibits the best humidity sensitivity. The humidity sensitivity is higher at lower frequencies with good temperature stability. The electrical conduction with water adsorption is dominated by the ions, and the activation energy decreases with increasing relative humidity
