Approximately 40% of all platinum demand comes from catalytic applications. In automotive catalytic converters, platinum converts harmful exhaust gases — carbon monoxide, hydrocarbons, and nitrogen oxides — into less harmful nitrogen, carbon dioxide, and water vapor. Beyond automotive use, platinum catalysts are essential in petroleum refining (catalytic reforming to produce high-octane gasoline), chemical manufacturing (production of nitric acid, silicones, fertilizers), and pharmaceutical synthesis. Platinum's exceptional resistance to corrosion and ability to operate at extreme temperatures make it irreplaceable in these applications.

Platinum is one of the most prestigious materials in fine jewelry, prized for its natural white luster, exceptional durability, and rarity. Jewelry-grade platinum is typically 950 parts per thousand pure (95%), with the remaining 5% consisting of other platinum group metals like ruthenium or iridium for added strength. Its hypoallergenic properties make it ideal for engagement rings, wedding bands, and luxury watches. Unlike white gold, platinum does not require rhodium plating to maintain its color, and it develops a unique patina over time that can be polished back to its original brilliance.

Platinum serves as both a precious metal and a strategic industrial commodity, offering investors a unique combination of safe-haven characteristics and exposure to industrial growth cycles. Investment-grade platinum is available in various forms — bars and ingots (typically 1g to 1kg), platinum coins (such as American Platinum Eagle, Canadian Maple Leaf, Australian Platypus), and exchange-traded funds (ETFs) backed by physical platinum. Investors are attracted by platinum's scarcity (only ~190 tonnes mined annually compared to 3,000+ tonnes of gold), its critical role in clean energy technologies, and its potential for price appreciation as industrial demand grows.

Platinum has been used in dentistry for over a century due to its biocompatibility, corrosion resistance, and strength. It is alloyed with gold to create high-grade dental restorations such as crowns, bridges, inlays, and onlays, where it adds hardness and durability without compromising biocompatibility. Platinum-containing alloys are particularly valued in posterior restorations where chewing forces are highest. The metal does not react with bodily fluids, does not cause allergic reactions in most patients, and maintains its integrity for decades — making it a premium choice for long-lasting dental work despite its higher cost.
