What are the uses of rhodium?
The major use of rhodium is in catalytic converters for cars (80%). It reduces nitrogen oxides in exhaust gases. Rhodium is also used as catalysts in the chemical industry, for making nitric acid, acetic acid and hydrogenation reactions.
What are the properties of rhodium?
Rhodium metal is lustrous and silvery white. Rhodium has a higher melting point and lower density than platinum. It has a high reflectance and is hard and durable. Upon heating it turns to the oxide when red and at higher temperatures turns back to the element.
What are the properties of lithium?
Lithium Properties Lithium has a melting point of 180.54 C, a boiling point of 1342 C, a specific gravity of 0.534 (20 C), and a valence of 1. It is the lightest of the metals, with a density approximately half that of water. Under ordinary conditions, lithium is the least dense of the solid elements.

Where is rhodium in electronics?
Rhodium Electroplating for Electronics Along with the other platinum group metals, rhodium can be found in platinum or nickel ores. Rhodium is also very hard and extremely durable — it will not form an oxide even under extreme temperatures. In fact, rhodium’s melting point is higher than that of platinum.
Is rhodium expensive than gold?
One of the most valued precious metals is rhodium. Rhodium prices are, in fact, far greater than gold prices. Due to its rarity, rhodium is only available in a fraction of the amount of gold. The large price disparity between gold and rhodium is due to the fact that gold mines are far more numerous than rhodium mines.
Why rhodium is expensive?
Rhodium is an ultra-shiny, corrosion resistant metal that had become useful in many industries including the automobile, jewelry, chemical and electrical trades. According to Peterson, it’s rhodium’s scarcity and use that makes it so valuable.
What are the dangers of rhodium?
* Rhodium powder can affect you when breathed in. * Contact can irritate the skin and eyes. * Rhodium powder may cause a skin allergy. If allergy develops, very low future exposure can cause itching and a skin rash.

What are 5 common uses of lithium?
Lithium and its compounds have several industrial applications, including heat-resistant glass and ceramics, lithium grease lubricants, flux additives for iron, steel and aluminium production, lithium batteries, and lithium-ion batteries. These uses consume more than three-quarters of lithium production.
How does rhodium react with chlorine?
Reactions with halogens Under anhydrous conditions rhodium will form trihalides with fluorine, chlorine and bromine.
