Abstract
Structural analysis using synchrotron radiation, such as X-ray diffraction (XRD) and X-ray absorption fine structure (XAFS), is an effective means of investigating physical properties of materials at high temperatures in order to experimentally clarify their physical properties. However, accurate temperature measurements above 2,800 K are difficult, complicating the assessment of structural changes in materials. This study addresses these issues by employing a newly developed furnace capable of reaching 2,800 K and performing in situ rapid XAFS and XRD measurements. These advances will improve our understanding of metal oxides at melting points and provide valuable insights into their behavior under extreme conditions.
