Description
A mineral composed of Calcium oxide and Titanium dioxide. Perovskite occurs in nature in Russia and was discovered in 1839 by Gustav Rose. The transparent to opaque stone varies in color from yellow to dark brown. Perovskite has also been made synthetically and is used primarily as a matrix for catalysts.
