Description and Uses

Use in the catalytic converters of automobiles. It is also used as an industrial catalyst in the manufacturing of chemical intermediates such as oxo-alcohols, as well as nitric acid and ethanoic (acetic) acid production. It is also an area of interest for new capacitor electrode material researchers, dynamic random access memory (DRAMs) and non volatile random access memories (FeRAMs) makers.
