Abstract
Time-resolved observations of phase transitions and solid reactions have been undertaken by angular dispersive powder diffraction at high temperature and pressure using the curved position sensitive detector (PSD) . The PSD streamer mode has a great advantage for the in situ observations of the structure changes within a few seconds because of high photon count efficiency of more than 70% and high angular resolution of 0.06° in 2θ.A Computer Aided Measurement And Control (CAMAC) System was applied to the time-resolved measurement of the diffraction intensities. An ADC having a 450MHz fast converter and histogram memory were installed in the system. The in situ observation of the pressure-induced amorphization of GeO2 using diamond anvil pressure cell and kinetic studies of dehydration of alkaline earth hydroxides at high temperature are presented in this paper.
