Abstract: In this work, barium zirconium titanate (BZT) ceramics were fabricated by using a ultrasonic ball milling technique. BZT with the ratio of BaCO 3ZrO2TiO2 was 1:0.05:0.95 was mixed in ultrasonic ball milling for 1, 3 and 4.5 hr and calcined at temperature of 1000 °C. Phase formation of BZT powder was investigated using XRD technique. Moreover, physical and electrical properties were examined. It was found that the tetragonal structure of BZT can be observed. Particle size of sample powder obtained from new milling technique is smaller than that of powder obtained from conventional mixed oxide method. Moreover, this new technique also requires the less time fabrication. Furthermore, the dielectric properties are increased with milling time and sintering temperature. © 2008 Trans Tech Publications, Switzerland.
