High-Pressure Synthesis, Crystal Structures and Physical Properties of Perovskite-Related 5d Transition Metal Oxides
概要
1.1. Crystal structure
Crystal structure is defined as the ordered repetitive arrangement of atoms, ions or
molecules in a solid material. Investigation of crystal structures has been a significant subject
beneficial for materials science study and search of new useful materials due to the strong
entanglement between the structure and properties of materials. In solid-state chemistry
research region, ABO3-type oxides occupy a prominent position since plenty of attractive oxide
compounds could be categorized in it, including Lithium niobite (LiNbO3) structure, perovskite
structure, corundum structure, ilmenite structure, KSbO3-type structure and so on. The study
on crystal structure is the basis of the present study, and I will therefore begin with a brief
introduction and description of the crystal structures involved in this paper, mainly the KSbO3type structure and perovskite structures. ...
