Rhodium is often a rare platinum team metallic (PGM) that may be chemically stable at substantial temperatures, proof against corrosion and primarily used in the production of automobile catalytic converters.
Wollaston known as on the list of new metals rhodium — rooted while in the Greek word for rose, "rhodon" — due to reddish salts that experienced dissolved within the aqua regia. (Aqua regia is usually a yellow-orange, fuming liquid, so-named by alchemists mainly because it can dissolve the noble metals gold and platinum.)
On the list of defining options of Rhodium is its outstanding resistance to oxidation. Compared with iron, which commonly kinds an oxide layer when exposed to oxygen, Rhodium stays nearly unchanged.
Rhodium is often alloyed with platinum and iridium to help make an oxidation-resistant metallic which will stand towards higher temperatures.

It might have been less costly to acquire silver-shiny rhodium steel alternatively. Even so, This is able to are impractical as this noble platinum-team ingredient is amongst the the very least reactive metals of your periodic desk. It reacts only reluctantly Using the alchemist's well known aqua regia, the powerful mixture try this web-site of concentrated nitric and hydrochloric acids that simply dissolves gold.
The chemical aspect rhodium immediately after processing being a powder, being a pressed cylinder and like a remelted pellet.

Open-pit mining is sometimes Utilized in spots exactly where the metal is located close to the area, though shaft mining is frequently employed in deeper deposits. In each situations, the ore has to be crushed and addressed with acids to extract the Rhodium from the ore.
Rhodium is renowned for its minimal chemical reactivity, particularly when compared to other transition metals. This restricted reactivity usually makes it a material of choice for numerous higher-efficiency applications.
Investing: Rhodium is also a sexy option for investors on account of its balance and possible for appreciation. Numerous investors view rhodium for a hedge towards inflation and possible market volatility.
