Gold is a highly valued metal with a wide array of uses that go far beyond jewelry and investment. Its unique properties—such as high electrical conductivity, corrosion resistance, malleability, and biocompatibility—make it essential in many industries[7].
- Electronics and Computing: Gold is extensively used in electronic components. Its conductivity and resistance to corrosion make it ideal for connectors, switches, circuit boards, and memory chips in devices like smartphones, computers, GPS units, and televisions. Even small quantities play a critical role in the reliable operation of these devices[1][2][3][5][6]. For example, an average smartphone contains about 50 milligrams of gold[3][5].
- Aerospace: Gold is used in aerospace applications such as satellite components and spacesuits. Its reflective properties help shield spacecraft and astronauts from solar radiation and extreme temperatures in space[1][6][7].
- Medical and Dentistry: Gold’s biocompatibility ensures its use in dental work (fillings, crowns, bridges) and some medical devices and surgical instruments. Its use in medical imaging and diagnostics is expanding, particularly with gold nanoparticles[3][7].
- Industrial and Chemical: Gold is used in coatings for optical equipment (like mirrors and lenses) due to its reflectivity and non-tarnishing properties. It is also being explored for use as a catalyst in chemical processes, including green energy and pollution control applications[1][7].
- Automotive: Gold is found in automotive electronics, such as engine control units (ECUs), sensors, connectors, and safety systems where reliable low-voltage connections are critical[1][8].
- Glassmaking and Decorative Uses: Gold is used to produce colored glass, gold leaf, and decorative applications due to its malleability and appearance[5].
- Renewable Energy: Gold’s conductivity and flexibility are exploited in emerging applications like organic photovoltaic cells and flexible electronics, supporting advances in solar energy and wearable technologies[2][7].
Despite accounting for only about 8–11% of annual gold demand, industrial and technological uses remain crucial, ensuring that gold’s relevance continues to grow with advances in science and technology[2][7].
