摘要
A new furnace for synchrotron X-ray powder diffraction experiments in a high-temperature range up to 1600degreesC has been developed in order to obtain the detailed crystallographic information around high-temperature structural phase transition for the diffractometer of the beam-line 3A at the Photon Factory. The new furnace optical design is based on the flat-specimen reflection geometry using a parallel beam. We have successfully acquired the electron density distribution map of CaTiO3 at about 1300degreesC with this new furnace using Rietveld and maximumentropy-method analysis.
