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