When the crystallography of the system is well known, the refinement of
the crystalline structure of the phases in the samples does not present any
problem when they are nonastructured.=20
In the case of alumina system, the different phases that appear are not
well understood, which difficulties their refinement; but for refining the
crystalline structure of alumina phases, the paper of Snyder, cited by by
Linda B. Mansker, is a good starting reference.
