MICROWAVE CHARACTERISTICS AND FAR-INFRARED REFLECTION SPECTRA OF ZIRCONIUM TIN TITANATE DIELECTRICS

The lattice vibrations of zirconium titanate containing SnO2 in solid solution were investigated using Fourier transform-infrared spectrophotometry. Microwave dielectric functions were determined by the Kramers-Kronig analysis followed by the classical dispersion analysis of infrared reflection spectra. The relative tendency of the spectroscopically determined dielectric functions is in agreement with those directly measured. For comparative studies or for the development of new microwave ceramic materials, the method is promising.
