Platinum is a versatile metal with major applications across multiple industries, owing to its unique physical and chemical properties[1].
- Autocatalysts: The largest use of platinum is in catalytic converters for vehicles, where it helps convert harmful exhaust gases—such as carbon monoxide, hydrocarbons, and nitrogen oxides—into less harmful substances like carbon dioxide, nitrogen, and water vapor. Over 95% of new vehicles contain platinum-based catalytic converters, making this a key end-use[1][7].
- Chemicals Industry: Platinum is widely used as a catalyst in the chemical industry, particularly in the production of nitric acid for fertilizers and explosives, as well as silicones, detergents, and plastics. Its catalytic properties speed up essential chemical reactions efficiently[1][3][2].
- Petroleum Refining: In refineries, platinum catalysts are essential for processes that convert crude oil into higher-octane gasoline and valuable petrochemicals. It plays a vital role in increasing the yield and efficiency of petroleum products[3][4].
- Electrical and Electronic Applications: Thanks to its excellent electrical conductivity and resistance to corrosion, platinum is used in electrodes, thermocouples, sensors (such as for airbags and breathalyzers), and components within hard disk drives, contributing to reliable, high-density data storage[1][3].
- Glass Manufacturing: Platinum’s stability at high temperatures and non-reactivity make it essential for manufacturing high-quality glass, especially for LED screens and glass fiber. The metal withstands the intense heat required in these processes without contamination[1][8].
- Medical and Biomedical Devices: Its biocompatibility allows platinum to be used in medical devices like pacemakers, dental equipment, and cancer treatment drugs. It is a material of choice where safety and reliability inside the human body are required[1][8].
- Hydrogen & Fuel Cells: Platinum serves as a catalyst in hydrogen fuel cells and electrolysis systems, which are pivotal for producing green hydrogen—a renewable and clean energy source—helping drive the transition to sustainable energy solutions[6][8].
- Jewelry: Platinum is also highly prized for making fine jewelry due to its luster, durability, and resistance to tarnish[7].
