Introduction to Pseudobrookites: Synthesis and Experimental Techniques

Abstract

The association of Tin with Lithium is found to be advantageous in Lithium-ion rechargeable batteries. The Substitution of Titanium by Tin in Fe₂TiO₅ enhances the dielectric properties. The polycrystalline pseudobrookite exhibits many interesting properties such as spin glass behaviour, thermal microcracking, magnetic texture, and high resistivity and has a wide range of applications. The characterization of LiAl intercalated and tin-containing iron titanates prepared by using rutile titanium oxide and sintered at 1250°C is explained in detail. The iron titanates are synthesized by the usual standard ceramic technique using A.R. grade oxides. The single-phase formation is confirmed by XRD and FTIR techniques. Structurally all the samples remain pseudobrookite having orthorhombic unit cells. That there is no loss of either Li¹⁺ or Al³⁺ is confirmed by the Inductively Coupled Plasma (ICP) and XRF technique. The magnetic hysteresis data for one of the samples shows that it is a soft ferrite. This book explains various methods of preparation of the ceramic samples of pseudobrookite compound and experimental measurement techniques to investigate their properties. The book balances theory and experimental work, showing how to link them together, which is suitable for students, researchers and academicians in the field of material science.
