Formula:
ZrTi2O6
Crystal System:
Orthorhombic
The occurrence of lamellae (in baddeleyite) of ordered ZrTi2O6 (orthorhombic space group Pbcn with a = 14.198 ± 0.002 Å, b = 5.326 ± 0.001 Å, c = 5.002 ± 0.001 Å). Single-crystal X-ray diffraction and Raman microspectroscopy results, including a calculated spectrum, are presented for the newly recognised ordered form of ZrTi2O6. In this phase, Zr is eight- and Ti is six-coordinated. It seems to be a hitherto unknown polymorph: So far, only disordered ZrTi2O6 with both Zr and Ti in octahedral sites was known to occur in nature. Revisiting known srilankite samples appears worthwhile.
