Many people buy and sell precious metals because they’re smart investments that often hold their value during times of economic uncertainty. However, most of them have unique properties that make them useful in other ways. You probably use items each day without knowing that they contain precious metals. Here are three industrial applications for gold, silver, and platinum.
Platinum Manages Auto Emissions
For decades, automakers have placed platinum in cars to limit the emission of carbon monoxide and other gas pollutants. As part of a vehicles’ catalytic converter, platinum’s chemical properties help break down toxic gases. Studies have shown that platinum can reduce the amount of toxic gases and particles in a vehicle’s exhaust by up to 90%. Platinum is also used in the fuel cells of vehicles that run on hydrogen instead of gasoline. Palladium can serve many of the same purposes as platinum, but it is a more expensive substitute, at least as of the time of this writing.
Gold in Space
Though gold coins and bullion are highly valuable here on Earth, gold is also used in the production of several objects that are launched into space. Because gold is highly conductive and resists rusting, it’s ideal for the circuitry of spaceships and space rovers. According to NASA, gold’s high conductivity can also protect astronauts and satellites from the extreme heat and radiation that occur in space.
Medical Uses for Silver
Silver can be found in remote controls, cameras, dentistry drills, and more, but one of its most important uses is in the medical field. This precious metal can kill bacteria, fungi, and even viruses. Scalpels, needles, and stethoscopes are often lined with silver to fend off hazardous microorganisms. Silver is also used in bandages and wound dressings to help prevent infections.
