Study of ceramic materials in the SrSnO3–NaNbO3 system by X-ray diffraction, dielectric and Raman spectroscopy
چکیده انگلیسی

Ceramics with composition belonging to the SrSnO3–NaNbO3 system were sintered in the temperature range 1100–1350 °C. The symmetry, dielectric properties and Raman spectroscopy were investigated. X-ray diffraction results demonstrate that a region with the cubic or tetragonal phases lies in the composition range x < 0.89 and x ≥ 0.89, respectively.The thermal behavior of the dielectric permittivity suggests the existence of two phases: cubic—paraelectric and tetragonal—ferroelectric or ferroelectric relaxor.The Raman spectra was recorded at room temperature and their evolution related to the chemical composition.
