Our XRD lab has only PDF2 database (ICDD), which i use with Brukers EVA search/match software. I have to do rietveld refinement of my hydrated cement paste samples but i can't retrieve cif files from PDF2 database. The phases that i have identified with the search/match option do have structural information. Just wondering if there is any way/software to create cif files, if the structural information like values of a,b,c, volume, density etc. are available
