High Energy Ball-Milling of Tin Titanate Zirconate for Use in Microwave Applications

Abstract:

Tin titanate zirconate (ZTS) is widely known for its good dielectric properties at high frequencies and has been widely employed as a dielectric resonator. ZTS does not sinter easily by solid state difusion and it is necessary to introduce sintering aids capable of increasing diffusion coefficients and/or leading to liquid phase sintering. Consequently, the dielectric properties in microwave frequencies can be reduced. This work focused on the utilization of high energy ball-milling as a method of reducing initial particle size and further improving sintering of ZTS.The powders obtained were characterized by X-ray diffraction as a function of milling time, as well as by a light scattering particle size analyzer.
