摘要:
Lead-free solid solutions (1-x)Ba-0.06(Na1/2Bi1/2)(0.94)TiO3-xNaNbO(3) (0 <= x <= 1.0) were prepared by conventional ceramic fabrication technique. X-ray diffraction and Rietveld refinement analyses of these ceramics were carried out using X'Pert HighScore Plus software to determine the crystal symmetry, space group and unit cell dimensions. Rietveld refinement revealed that NaNbO3 with orthorhombic structure was completely diffused into Ba-0.06(Na1/2Bi1/2)(0.94)TiO3 lattice having the rhombohedral-tetragonal symmetry. EDS and SEM studies were carried out in order to evaluate the quality and purity of the compounds. SEM images showed a change in grain shape with the increase of NaNbO3 content. FTIR spectra confirmed the formation of solid solution.
