Nature of the physical problem PROVA calculates the X-ray intensity diffracted from powders constituted by generic domains, whatever the dimensions of each domain along the three crystallographic axes, possibly disordered, having unit cells belonging to any crystal system. ## Method of solution T
The crystal structure of anosovite, (Ti 1.69 Al 0.26 Fe 0.05 ) 3+ (Ti 0.97 Zr 0.03 ) 4+ O 5 , prepared by carbothermal reduction of leucoxene under vacuum at 1450ยฐC has been refined by Rietveld method using powder X-ray diffraction data. It was found that it represents slightly monoclinically deform
