Investigating the Effect of Temperature and Phase on Properties of Metal Pseudobrookite

August 31, 2021 Chemical Science 0

Spin glass behaviour, thermal microcracking, magnetic roughness, and high resistivity are all characteristics of iron titanate, a metal pseudobrookite. Pseudobrookite is a polycrystalline pseudobrookite that has a wide range of uses. The electrical resistivity and dielectric properties of pure iron titanates prepared with the rutile form of titanium oxide and sintered at two temperatures, 1000oC and 1250oC, as well as pure iron titanates prepared with the anatase form of titanium oxide and sintered at 1250oC, are compared in this paper as a function of temperature and relaxation spectra. The iron titanates are manufactured with A.R. grade oxides and a traditional ceramic process. The formation of a single phase is confirmed by XRD and FTIR studies. All of the samples are pseudobrookites with orthorhombic unit cells in terms of structure. For the pseudobrookite made from rutile TiO2, study of the relaxation spectra reveals the existence of space-charge, which increases with sintering temperature. According to the research, pseudobrookite produced from anatase TiO2 has worse dielectric and electric properties at lower frequencies (1 kHz) and exhibits substantial hysteresis, indicating delayed microcrack healing. The impact of structural alterations on resistivity, dielectric constant, and dielectric loss are examined.
