Research Abstract |
In the field of structural mineralogy, much attention has been paid to the nano-meter sized middle range ordering with a mezzo-scopic structure. Present study focuses on AXS-RMC analyses of natural chrysocolla and synthetic naegite, and discusses the relationship between their middle range ordering structures and unique crystallization procedures. Additionally, the structures of Zr-Pd and ZrPt amorphous metals with their unique crystallization process of an icosahedral phase, have been studied by means of AXS-RMC technique. The results of this study can be obtained only by the unique and advanced AXS-RMC method by the high energy X-ray diffraction and anomalous X-ray scattering together with reverse Monte Carlo simulation.
