Applications

Used as a catalytic convertor in automobiles. It is also employed as an industrial catalyst in the manufacturing of chemical intermediates such as oxo-alcohols, as well as nitric acid and ethanoic (acetic) acid productions. It is, likewise, of interest for new capacitor electrode materials, dynamic random access memories (DRAMs) and non-volatile random access memories (FeRAMs).

Notes

Avoid extreme heat, organic solvents, hydrochloric acid, hydrosulfuric acid and ammonia.
