Ruthenium is a silver-white metal with a density of 12.3, a melting point of 2310 and a boiling point of 3900. Ruthenium is not vivid in chemical properties, insoluble in acid and acid, soluble in molten alkali, carbonate, etc. React with fluorine, chlorine, etc. When heated, ruthenium has a strong tendency to form coordination compounds and has excellent catalytic function.
Now more than 80 kinds of platinum group and platinum group ELEMENT-BEARING deposits have been discovered, and more than 200 varieties and undefined deposits have been found. In the natural world, platinum group metals exist mainly as Natural elements, natural alloys, antimony, sulfide, arsenide and bismuth telluride, and some of them are isomorphic in sulfides, such as chalcopyrite, nickel pyrite and purple sulfur nickel (iron) ore. In the ore containing platinum group elements, because osmium Iridium, palladium, rhodium and ruthenium all coexist with platinum, platinum is usually the main component, while other platinum group elements are relatively small, so ruthenium and other platinum group metals are recovered from the residue after platinum extraction.
Ruthenium is a useful hardener for platinum and palladium. Ruthenium is used to make electrical touch alloys. The corrosion resistance of titanium metal can be greatly improved by adding 0.1% Ruthenium. Ruthenium-molybdenum alloy is a superconductor. Ruthenium-containing catalysts are mostly used In petrochemical industry.
