PERIODIC Investments

Gold is used in jewellery and as an investment and store of value, but also has vital industrial uses in electronics, medicine, dentistry, and aerospace, thanks to its properties of excellent electrical and thermal conductivity, malleability, ductility, and resistance to corrosion and tarnish.  
Here's a breakdown of its main uses:
Jewellery 

• Gold's beauty and rarity have made it a popular metal for ornaments, rings, watches, and other decorative items.

Investment and Finance 

• It's a traditional store of value and a popular investment, with demand for gold bars and coins remaining strong, particularly as a "safe-haven asset" during market downturns.

Electronics 

• Gold's excellent electrical conductivity and resistance to corrosion make it ideal for connectors and components in devices like smartphones, computers, and other electronic equipment, where even slight corrosion can disrupt low-voltage currents.

Medicine and Dentistry

• It's used in dental fillings and prosthetics due to its inertness and compatibility with body tissues. 

• Certain gold compounds are also used in treatments for conditions like arthritis, and gold nanoparticles are being explored for diagnostic tools and treatments. 

Aerospace 

• Gold is used to coat materials in spacecraft to reflect infrared radiation and protect against the harsh conditions of space. It's also used in some satellite temperature control systems.

Other Industrial Uses

• Glassmaking:
  Thin gold films are used on large office windows to control heat gain and reduce glare. 

• Catalysis:
  Gold acts as a catalyst in industrial processes, such as the production of vinyl acetate, a key component for paints and adhesives.
