Perovskite

Name:
Perovskite
Detailed information:
A natural or synthetic crystalline mineral composed of calcium dioxide and titanium dioxide. The natural material was discovered in Russia in about 1850; the synthetic type can be so made as to incorporate particles of catalysts (platinum or palladium), that are protected by the crystalline structure from contamination by lead and other poisons, thus permitting use of leaded gasoline in cars equipped with emission-control devices.
