This lecture discusses the fundamentals and applications of inorganic materials, their crystal structures and their structure-property correlations. In this lecture, I describe the experimental techniques such as X-ray powder diffraction, synchrotron X-ray powder diffraction, neutron powder diffraction and Raman scattering, which are important in the characterization of industrial materials. I also present the analysis techniques as Rietveld method and maximum-entropy method. We discuss the structure-property correlation of materials for clean energy and environments (solid oxide fuel cells, exhaust gas catalyst) and ferroelectric materials.
By this lecture, the students aim to understand the crystal structure of inorganic materials at an atomic scale, to discuss the correlation between structure and properties, and to design the materials.
You will be able …
1) to understand the structure and property of inorganic materials at an atomic scale and at an electronic level
2) to understand the literature including the crystallographic data and results of crystal structure analysis.
3) to draw and understand the crystal structure
4) to estimate the interatomic distances, bond angles, coordination number and bond valence sum (BVS).
