Abstract In the first chapter of the thesis, a general review of the groperties of BaTi03 , YbZrO? ocrmnics aai: solid solutions containing BalJiO or PbZrO is briefly prescntcd . 3 3 Chapter two comp~ises the exper5xental rilethods adopted for the preparation of %Ti0 3 and PbZyO 3 cerzmics, using solid st7.te rc~ctioon. Elor ideotif ic~tion of the prcepzred rnz,teriz,ls, X -rcy diffraction pztterns zad spectroscopic analysis were dom. In this cixpter clso the method of prepmine (EzY~G-~ ~ bZr0~)co inpositions for the oresent nork and their X -ray diffraction patterns are given. The experimental methods followed in measuring the density, dielectric constant, losses =nd D, C. resistivity of the samples are described, Chzpter thzec deals 7;~ith %he study of the effect of introducing different oercentnges of PbZr03 , to the (3-q” Y IO~ - PbZrO 3 ) compositions, on their dielectric and electrical groperties. Conventional measuring techxiquex 2.t different temperatures yielded 2 lot of information about the prepared s=lmples, The results obt2ined aTe in ;_:!myr espects in agreement with the literatuxe dntz on solid solutions 02 these mc-Lerinls, |
