Ruthenium belongs to the platinum group metals (PGMs) and is exceedingly rare. Worldwide annual production is estimated between 12 and 20 tonnes of ruthenium compared to 2700 tonnes of gold. It is corrosion and wear resistant and its alloys can be superconductive. It has other unusual and unique properties and has applications in electronics, chemical and solar power industries.
The chemical properties of Ruthenium are not vivid, insoluble in acid, soluble in molten strong alkali, carbonate, etc.; when heated, it can react with fluorine, chlorine and reverberation; Ruthenium has a strong tendency to form a coordination compound and has outstanding catalytic function.
Ruthenium is a useful hardener for platinum and palladium. It is used to make electric touch alloys. The participation of 0.1% niobium in titanium metal can greatly improve the corrosion resistance. Ruthenium molybdenum alloy is a kind of superconductor, and Ruthenium-containing catalyst is mostly used in petrochemical industry.
