Which is more used in industry, gold or silver?

Silver is widely used in industry, and the proportion of industrial gold in the total world demand is less than 10%. In the electronic industry, the biggest use of silver is thick film paste, which is usually used to make screen printed circuits in multilayer ceramic capacitors, thin film switches, heating films for automobile rear windshields and conductive adhesives.

Silver has a unique light reflectivity, and the reflectivity after polishing reaches 100%, which can be used on mirrors, glass, cellophane or metal. Many batteries, rechargeable batteries and disposable batteries use silver alloy as cathode. Although expensive, the energy of silver-containing batteries is better than other types of batteries. The most common is the button-sized silver oxide battery (containing 35% silver), which is usually used in watches, cameras and similar electronic products.

A large number of chemical reactions use reticulated and crystalline silver as catalysts. For example, silver is used as a catalyst for formaldehyde in plastic production and for ethylene oxidation in petrochemical industry. The flexibility and strength of silver promote the connection of materials (above 600℃ is called brazing, hereinafter referred to as soft welding). Silver brazing alloy has a wide range of applications, from power equipment such as air conditioners and refrigerators to automobile, aerospace and aviation industries. Compared with other bearings, bearings plated with pure silver have higher fatigue strength and bearing capacity, so they are used in various high-tech and heavy-load occasions.
