A natural sample of perovskite (calcium caesium sodium iron titanium oxide) from the Tapira Alkaline Complex in southeastern Brazil was found by electron microprobe analysis to have the chemical formula (Ca(2+) (0.95 (1))Ce(3+) (0.011 (2))Na(+) (0.010 (4)))(Fe(3+) (0.022 (2))Ti(4+) (0.98 (1)))O(2−)...

description A natural sample of perovskite (calcium caesium sodium iron titanium oxide) from the Tapira Alkaline Complex in southeastern Brazil was found by electron microprobe analysis to have the chemical formula (Ca(2+) (0.95 (1))Ce(3+) (0.011 (2))Na(+) (0.010 (4)))(Fe(3+) (0.022 (2))Ti(4+) (0.98 (1)))O(2−) (3) and by IR spectroscopy to be an anhydrous mineral. Oxygen anions are arranged around Ti(4+) in an almost perfect octa­hedron and around Ca(2+) in a distorted 12-fold polyhedron.
