RUTHENIUM



Ruthenium is primarily used for wear-resistant electrical contacts and the 


production of thick-film resistors. Ruthenium is one of the most effective hardeners 


for platinum and palladium and is alloyed with these metals to make electrical 


contacts for extremely wear resistant electronics and laboratory equipment. The 


corrosion resistance of titanium is improved a hundredfold by the addition of 0.1% 


ruthenium. Ruthenium is also a versatile catalyst. Hydrogen sulfide can be split 


catalytically by light using an aqueous suspension of cadmium sulfide particles 


loaded with ruthenium dioxide. Ruthenium is available as metal and compounds 


with purities from 99% to 99.999% (ACS grade to ultra-high purity).  High Purity 


(99.999%) Ruthenium (Ru) Sputtering TargetHigh Purity (99.999%) Ruthenium 


Oxide (RuO2·xH2O)PowderElemental or metallic forms include pellets, rod, wire 


and granules for evaporation source material purposes. Ruthenium nanoparticles 


and nanopowders provide ultra-high surface area. Ruthenium oxides are available 


in powder and dense pellet form for such uses as optical coating and thin film 


applications. Oxides tend to be insoluble. Fluorides are another insoluble form for 


uses in which oxygen is undesirable such as metallurgy, chemical and physical 


vapor deposition and in some optical coatings. Ruthenium is also available in 


soluble forms including chlorides, nitrates and acetates. These compounds can be 


manufactured as solutions at specified stoichiometries.
