| Description: |
Barium Titanate synthesized by the oxalate coprecipitation method was doped by other perovskite-based material PbZrO 3 and NaVO 3 to obtain a system of (1-x-y)BaTiO 3 -xPbZrO 3 -yNaVO 3 with x = 0.15 and y = 0.025. TGA characterization shows an important weight loss that starts at 400°C and finished at 650°C. XRD analysis of calcined powder at 650°C shows that the samples mostly consist of single-phase BaTiO 3 perovskite. Sintering process was carried out in two ways; first, a single step sintering up to 1250°C for 2 hours shows increasing secondary phases, until the BaTiO 3 phase becomes the minority. Secondly, multistep sintering starting at 1050°C, holding for 2 hours, down to room temperature, and then repeated with similar processes for 1150°C and 1250°C. Characterizations including XRD, SEM for microstructure, and permittivity analysis of the sample after this thermal treatment shows that the majority phase is BaTiO 3 with minor secondary BaVO 2.9 phase and its electrical properties are enhanced. |
