What is Rhodium

Rhodium (Rh) is a rare, silvery-white transition metal that belongs to the platinum group of metals. It is known for its exceptional hardness, high reflectance, and resistance to corrosion. Rhodium is typically found in platinum or nickel ores and is one of the rarest and most valuable precious metals. Its rarity and unique properties make it highly sought after in various industrial and commercial applications.
