O knihe

This book provides a detailed introduction to the preparation and characterization of microwave dielectric materials. Dielectric and structural investigation on Sr1-3x/2CexTiO3 (x=0.133 to 0.4) based ceramics is also presented. These materials posses high permittivity varying from 113 to 180 and quality factor of 8000 to 11000 GHz at 2 GHz and relatively high temperature coefficient of resonant frequency (tf). While no superlattice can be observed via x-ray diffraction or vibrational spectroscopy, both electron and neutron diffraction show evidence of a non-cubic super-cell caused by anti-phase tilting of oxygen octahedra. Pb substitution for Sr induces a ferroelectric transition.
