| Abstract | ||
| BaxSr1-xTiO3 (BST) ferroelectric nano, poly crystalline systems were processed with three concentrations (x = 0.5, 0.7 and 0.9) using a technique known as oxalic acid route. The XRD spectra were analyzed, and used Scherer formula to estimate the crystallite size of the products, which reached to 15.4 nm at x = 0.5. It is found that increasing of Sr+2 cations help to decrease the crystallite size of BaxSr1-xTiO3 system and the tetragonality c/a increases when the crystallite size increases. In physical tests we conclude that the oxalic acid method is a good method to prepare a BST ferroelectric phase with high density (5.05, 5.5 and 5.45) gm/cm3, and small porosity (16, 8, and11) % for (x = 0.5, 0.7 and 0.9) respectively. | ||
