PLATINUM GROUP Meaning and
Definition
-
The term "platinum group" refers to a specific group of six metallic elements that share similar properties and chemical characteristics. These elements are platinum, palladium, rhodium, ruthenium, iridium, and osmium. They are collectively referred to as the platinum group metals (PGMs).
Platinum, the most well-known and prominent element of this group, is a precious metal with a silver-white appearance, high melting point, and exceptional resistance to corrosion. Palladium, another widely recognized element, is renowned for its catalytic properties and its extensive use in the automotive industry. Rhodium is highly valued for its reflective and corrosive-resistant properties, often used in the production of mirrors and jewelry. Ruthenium, though less commonly known, has corrosion resistance and electrical conductivity properties that make it useful in various industrial applications. Iridium is the densest and most corrosion-resistant element in the group, with applications in spark plugs and electrical contacts. Lastly, osmium is known for its extremely high melting point and has applications in specialized alloys and fountain pen tips.
These platinum group metals are coveted for their unique properties, including their rarity, durability, and catalytic activity. Due to their scarcity and desirable characteristics, they are highly valued in various industries such as jewelry production, electronics manufacturing, automotive catalysts, and many more. The platinum group metals serve as critical components in technological advancements and are considered crucial for sustainable development and the transition to cleaner energy sources.
