PREPARATION AND ANALYSIS OF BaPr(1.33)Ti(3)O(9) & BaPr(2)Ti(4)O(12) MICROWAVE DIELECTRIC CERAMICS
In the field of micro wave dielectric ceramics, BaO-R 2 O 3 -TiO 2 ( R =La, Nd, Sm, Pr ) is the most valuable material system, which is used for microwave components such as multi-layer ceramic chip capacitor (MLCC), single-layer ceramic chip capacitor (SLC), dielect ric resonator & filter, voltage control oscillator (VCO) and antenna, etc . Also microwave dielectric ceramics has received much attention due to rapid growth of the wireless communication industry. In this project we are concerned with the development of microwave resonator materials. The three vital properties required for these materials are: 1) A high dielectric constant for miniaturization. 2) A high quality factor (which is inverse of loss tangent, tanĪ“) for better frequency stability. 3) A good temperature stability or near zero temperature coefficient of resonant frequency. Dielectric ceramics materials in ternary system BaO-R 2 O 3 -TiO 2 (R=Rare earth, La, Pr, Nd, Sm, Gd) has ga
