PREPARATION, CHARACTERIZATION AND DIELECTRIC-PROPERTIES OF CERAMICS IN THE BAO-ND2O3-TIO2 SYSTEM

The dielectric ceramics BaNd2Ti3O10, BaNd2Ti4O12 and BaNd2Ti5O14 have been prepared by conventional solid state ceramic route. The sintered ceramic samples have been characterised by X-ray diffraction and Scann ing Electron Microscopy (SEM). The dielectric properties in the microw ave frequency range have been measured using conventional microwave di electric resonator methods. The BaNd2Ti3O10, BaN2Ti4O12 and BaNd2Ti5O1 4 have dielectric constants (epsilon(r)) similar to 60, 84 and 77 resp ectively. They have relatively high quality factors.
