Platinum was first used in the early 19th century, which was thought to be used to make saucepans for storing concentrated sulfuric acid because it was chemically stable.
Besides that, platinum also has good ductility and can be processed into micron fine wire and platinum sheet, so platinum is made into the crucible, distillation kettle, electrode, pipe, platinum-plate, filter screen, and anti-acid and anti-heat equipment in chemical laboratories and l factories.
Moreover, platinum also reduces corrosion by sea water on ships and prevents the growth and accumulation of Marine life, which solves a vexing problem for seafarers.
In nature, platinum group elements together with gold and silver are known as precious metal elements. Platinum family has platinum, iridium, rhodium, and palladium. The most important value of platinum is not that it is a platinum jewelry, but that it is an important industrial catalyst, such as in the aerospace fuel and new energy […]
The South American Indians knew platinum from an early age, and it is often found in sand grains in the form of natural platinum in nature. When the Spaniards arrived in South America, they called the natural platinum “Little silver” and brought it to Europe for the first time from Ulloa. The “Litter Silver” is […]
The platinum-group metals can be described as refractory metals because of their high melting points. This group comprises platinum, osmium, iridium, ruthenium, rhodium and palladium, i. e., metals which have properties similar to those of platinum. The metals in this group are quite scarce and, hence, can be considered only for very specialized applications even […]
