N2 - Powder X-ray diffraction patterns were collected from three titanate waste forms -a calcine powder, a prototype ceramic without waste, and a ceramic containing 10 wt% JW-A simulated waste- and interpreted quantitatively using the Rietveld method. The calcine consisted of fluorite, pyrochlore, rutile, and amorphous material. The prototype waste form contained rutile, hollandite, zirconolite and perovskite. The phase constitution of the JW-A ceramic was freudenbergite, loveringite, hollandite, zirconolite, perovskite and baddeleyite. Procedures for the collection of X-ray data are described, as are assumption inherent in the Rietveld approach. A selection of refined crystal data are presented.
