Nowadays, high dielectric materials are important materials in microwave electronic applications due to its properties that can provide high frequency range of an antenna. Barium Zinc Tantalate (BZT) is a complex perovskite structure that can produce high quality factor, Q. In this research, the effect of calcinations temperatures on phase formation, density and morphology of BZT powders were investigated. Based on the DTA result, the range of calcinations temperatures to be investigated were between 750°C to 1250°C. Results show that the maximum density of BZT occurred at 1150°C with 99.74% theoretical density. Samples calcined at below 1100°C still containing their basic raw materials such as BaCO3, ZnO and Ta2O5. The pure phase of BZT was formed at 1150°C when calcined for 1 hour. The lattice distortion of BZT increased when the calcinations temperature increased between 1000°C to 1150°C. The calcined powders show almost spherical morphology and agglomerated. The particle sizes of BZT decreased from 0.716 m to 0.258 m when the temperature increased from 750°C to 1200°C. 2010-11-01T08:02:04Z 2010-11-01T08:02:04Z 2010-06-09 Working Paper p.324-332 978-967-5760-02-0 http://hdl.handle.net/123456789/10151 en Proceedings of the International Conference on X-Rays & Related Techniques in Research & Industry (ICXRI) 2010 Universiti Malaysia Perlis School of Materials Engineering & School of Environmental Engineering |
