Hello, It depends what you want to do, Fullprof is a good sofware it you want refine your cell parameters, determine size particles or make a Rietveld affinment, and there is also another software "" expo2013"" it is free and for beginners it is easier.
If you want just compare your powder patern with PDF data base, it exists other software like ""Match"" for example. Hope it help you
Plz guide me how could i refine my cell parameters, and how to determine the size of particles. I have the data in UXD format and in UDF format. plz guide me. I am waiting for your positive reply. plz reply soon.
A suggestion: I often uses Maud to analyze my XRD data. It is written in java and its portability is excellent. Moreover, it is easier to manipulate than Fullprof, despite the fact that the latter is also good.
