Rhodium usage is dominated by autocatalyst applications where it is used together with platinum and palladium to control exhaust emissions
This increased supply was primarily responsible for a declining rhodium price during the 1990s.Interruptions to Russian supply since early 1997 have helped the rhodium price to recover strongly.
Rhodium it is unaffected by air and water up to 600 C. It is insoluble in most acids, including aqua regia, but is dissolved in hot concentrated sulfuric acid and it is attacked by molten alkalis.
Rhodium is too rare for the amount of it in soils or natural waters to be assessed, and so its effect on the environment can be assumed to be nil.
Rhodiumcatalysts have been prominently represented among such applications, exhibiting a scope and versatility that probably are unmatched by those of any other element.
Rhodium complexes, notably porphyrins, also exhibit distinctive patterns of reactivity toward C–H bonds.
Rhodium is also used as an electrical contact material, in jewelry, and as a catalyst.
Small and large samples of rhodium wire like this can be purchased via their web catalogue from from Advent Research Materials via their web catalogue.
Sometimes extraction of the preciousmetals such as rhodium, platinum and palladium is the main focus of a partiular industrial operation while in other cases it is a byproduct.
