Rhodium Powder has a corrosion resistance, even higher in boiling aqua regia. But the hydrogen bromate slightly corrodes rhodium. It is used as the raw materials for instrument, chemical industry and precision alloys. Wet iodine and sodium hypochlorite can corrode it. It has the chemical symbol Rh and atomic number 45. It is composed of only one isotope, 103Rh. Rhodium powder can be used as raw materials of electrical instruments, chemical engineering and manufacturing precision alloy etc. Rhodium is a chemical element that is a rare, silvery-white, hard and chemically inert transition metal and a member of the platinum group. Rhodium detectors are used in nuclear reactors to measure the neutron flux level. CAS:7440-16-6, Molecular Weight:102.91.
Rhodium is a so-called noble metal, resistant to corrosion, found in platinum- or nickel ores together with the other members of the platinum group metals. Molecular Formula: Rh The element's major use (about 80% of world rhodium production) is as one of the catalysts in the three-way catalytic converters of automobiles. Because rhodium metal is inert against corrosion and most aggressive chemicals, and because of its rarity, rhodium is usually alloyed with platinum or palladium and applied in high-temperature and corrosion-resistive coatings.
