The most important purpose of Rietveld analysis is the refinement of lattice and structure parameters. In addition, we can obtain geometric data (in turn, bond valence sums), magnetic moments (neutron diffraction), crystallite sizes, microstrains, and mass fractions. They are briefly described so that one can gain a better understanding of the information extractable from powder diffraction data.
