Dear Nelson Duarte,
Within the help system of HighScore Plus you will find various tutorial
examples about Rietveld analyses.
Just press the F1-key at any stage in the program to invoke the help
system.
These tutorials will guide you step by step. In particular I would
recommend you to look a
You would be well advised to do some background reading on microabsorption as
it will be pretty bad with those two phases and limit the accuracy you may
realistically expect in your quantification

Dear Nelson,
You can also often find structures of interest in the American
Mineralogist Crystal Structure database
(http://rruff.geo.arizona.edu/AMS/amcsd.php). Both of your phases are
listed numerous times in this data base, and you can download cif files.
The database is freely available.
Prezado Nelson,
You can find CIF files for both alumina and crocoite phases at the
Crystallography Open Database (www.crystallography.net) looking for
chemical elements.
An excellent set of educational material on Rietveld refinement using
