Solid solubility in the pseudo-binary TiO2—(FeSb)O4 (rutile — tripuhyite) system was investigated annealing powder mixtures characterized by different TiO2/(FeSb)O4 molar ratios in an O2 flux. Complete miscibility was found in the whole compositional range at 1373 K. The crystal structures of (FeSb)O4 and selected terms of the (Ti2xFe1-xSb1-x)O4 solid solution (0 ≤ x ≤ 1) were refined from X-ray powder diffraction data using the Rietveld method. Selective broadening of the X-ray lines was observed and analyzed by means of the Gaussian quadratic plot. Line broadening is probably related to a phase transformation taking place at low temperature, as suggested by the excess molar volume of the solid solution. As a result local chemical inhomogeneity and microstrain in the direction perpendicular to the 00l lattice planes for compositions 0.2 ≤ x ≤ 0.6 are generated. © 2004 Oldenbourg Wissenschaftsverlag GmbH Crystallography nationallicence Inorganic chemistry nationallicence Organic chemistry nationallicence Martinelli Alberto aut Ferretti Maurizio aut Basso Riccardo aut Cabella Roberto aut Lucchetti Gabriella aut Marescotti Pietro aut Buscaglia Vincenzo aut Zeitschrift für Kristallographie - Crystalline Materials De Gruyter Oldenbourg 219/8(2004-08-01), 487-493 2194-4946 219:8<487 2004 219 zkri https://doi.org/10.1524/zkri.219.8.487.38327 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/zkri.219.8.487.38327 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Martinelli Alberto aut NATIONALLICENCE 700 1- Ferretti Maurizio aut NATIONALLICENCE 700 1- Basso Riccardo aut NATIONALLICENCE 700 1- Cabella Roberto aut NATIONALLICENCE 700 1- Lucchetti Gabriella aut NATIONALLICENCE 700 1- Marescotti Pietro aut NATIONALLICENCE 700 1- Buscaglia Vincenzo aut NATIONALLICENCE 773 0- Zeitschrift für Kristallographie - Crystalline Materials De Gruyter Oldenbourg 219/8(2004-08-01), 487-493 2194-4946 219:8<487 2004 219 zkri CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
