Hi! I guess you have several diffractograms, don't you? you can work one by one your data, but first you must have data about the configuration of diffractometer or experimental data of an standard material like LaB6 and fit. after that you can replace the experimental data and fit. The temperature affects B ( thermal parameters), it is my suggestion, best ishes Miguel Hesiquio ----- Original Message ----- From: sisir ray To: rietveld_l@ill.fr Sent: Thursday, November 15, 2007 5:22 PM Subject: High temperature PXRD fitting in TOPAS Hi, I have got high temperature Powder xrd data (from lab xray source) in the range of 30 ~1000 C .
