Pure Rhodium

Rhodium is a silver-white metallic element which occurs in nature in association with the other platinum metals, and it is generally obtained commercially as a by-product of the extraction of nickel and copper from their ores. It is considered the rarest and most valuable precious metal in the world — well above gold or silver. Rhodium is highly reflective and resistant to corrosion. Upon heating it turns to the oxide when red and at higher temperatures turns back to the element. Rhodium it is unaffected by air and water up to 600℃. It is insoluble in most acids, including aqua regia, but is dissolved in hot concentrated sulfuric acid and it is attacked by molten alkalis.

Applications

Rhodium has a wide variety of application in diverse fields. Few of the applications of Rhodium are listed below:

• Since rhodium is quite brilliant and resistant to tarnishing, it is used as a finish for jewelry, searchlights, and mirrors.
• Electrodeposition of rhodium makes extremely hard coatings used in the manufacture of mirrors for optical instruments.
• Rhodium is rarely used by itself and almost always as an alloy. For instance, rhodium alloyed with platinum can be used in electronic devices implanted in the human body to treat specific conditions.
• Other uses for rhodium are coating optic fibers, laboratory crucibles, thermocouple elements, headlight reflectors, and bushings for drawing glass fibers.
