  • Platinum alloys often substitute for gold in electronic equipment. Today, the largest single application of platinum in the electronic industry is for the magnetic coating of computer hard drives.
  • Platinum-cobalt alloys are slightly magnetic. Today more than 90% of all computer hard drives are coated with this alloy, which enables the disks to store larger amounts of information.

Chemicals industry

Again acting as a catalyst to boost the speed and efficiency of chemical reactions, platinum is essential in producing many key industrial, agricultural, and household chemicals.

  • The greatest chemical demand for platinum comes from creating specialty silicones according to technology specialists Johnson Matthey.
  • Platinum compounds are used in everything from sealants to electrical wire insulation, and lubricants to kitchen utensils.
  • Petroleum refining – The most consistent industrial use of platinum over the last four decades is the oil refining industry uses the metal as a catalyst for ‘cracking’ low-grade fuel into more efficient forms including gasoline, diesel, and jet-engine fuel.
  • Glass manufacturing – Holding and channeling molten glass requires tools that can both withstand temperatures of 1700°C and also avoid corroding or reacting with the silicates and other materials used. Fiberglass is produced by drawing the glass through a platinum sieve called a ‘bushing’.

Automotive/Automobiles Industry

Platinum alloys play an important role in the defense and aerospace industries because they are incorporated into jet and rocket engines, which work in extremely hot and corrosive conditions caused by burning fuels. Platinum alloys are also used to coat the nosecones of missiles.

  • Platinum’s single heaviest use currently comes from the auto sector, where the metal is used to reduce harmful emissions, most notably from diesel engines.
  • The small rocket motors that maneuver satellites into place are also made of platinum alloys.
  • Used in the electronics of the engine, braking, and airbag deployment systems.
  • Platinum alloys resist spark and heat damage, thus used to coat the tops of spark plugs.
  • Platinum is a key component of the catalytic converters used to control automobile emissions.
  •  Placed in the exhaust system of a truck or car, a very fine coating of platinum speeds up the reaction of oxygen with both deadly carbon monoxide (CO) and hydrocarbons (so-called greenhouse gases), turning them into less harmful carbon dioxide (CO2) and water, and also reducing the output of sulfur particles.
  • Platinum-based coatings protect jet-engine blades (temperatures reach 2000°C); found on the tip of high-performance spark plugs, and fuel-cell technology is a fast-growing alternative to gasoline and diesel combustion engines.

Glass Manufacturing

Glass manufacturing using platinum metal involves the utilization of platinum as a catalyst in various stages of the process. Platinum possesses exceptional properties that make it suitable for this application. Firstly, it has a high melting point, allowing it to withstand the high temperatures required for glass production. Secondly, platinum is highly resistant to corrosion and chemical reactions, ensuring the purity of the glass product.

Additionally, platinum’s catalytic properties aid in the refining and purification of raw materials, enhancing the quality of the glass. Its use in glass manufacturing contributes to the production of high-quality, durable, and optically clear glass products across various industries, including automotive, construction, and electronics.
