Ruthenium has a strong tendency to form coordination compounds and has good catalytic properties. Ruthenium is an effective hardener for platinum and palladium; adding 0.1% ruthenium to titanium can greatly improve corrosion resistance; ruthenium-molybdenum alloy is a superconductor; catalysts containing ruthenium are mostly used in petrochemicals.
