Synthesis Of Nonatitnate Based Dielectric Ceramic Using Various Grain Size of Starting Materials

Parul, Anand K Tyagi

Abstract :

The technological advancements in the field of microwave communication owes to the availability of suitable and affordable electroceramic materials, called Dielectric Resonators (DRs). Ceramic dielectrics especially the complex titanates are the promising candidates as good DR material. There exists two important choices, namely; BaTi4 O9  and Ba2 Ti9 O20. The present work investigates the effect of particle size distribution among the reacting crystallites on faication of very dense bodies of Ba2 Ti9 O20 ceramic with phase purity. The Ba2 Ti9 O20 phase development and its dielectric characteristics are found to be highly sensitive to the particle size of starting materials, impurity phases evolved and porosity in the sintered products. It was found that most promising characteristics of the dielectric ceramics based on Ba2 Ti9 O20 were obtained when reagent powders were ground for 9 hrs.
