Other InformationHide

IR Spectrum:
The IR spectrum is an important diagnostic feature. Absorption bands (s = strong band, sh = shoulder) are 1013, 950sh, 892s, 849s (Si–O stretching vibrations), 670sh, 654 (O–Si–O bending vibrations of Si2O7 groups), 570, 526 (Ti–O stretching vibrations of TiO5 polyhedra), 454s, 389s (combination of Si–O–Si bending vibrations and stretching vibrations of MO6 octahedra, where M = Fe3+, Fe2+, Mn, Mg, Ca). Bands less 1100 cm–1 are not detected in the IR spectrum.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
