Why is platinum so important?

Because of its stable physical and chemical properties, platinum metal is a very useful metal. Despite its rarity, its application is quite widespread. Because of its high stability, platinum is used extensively as a catalyst for chemical reactions.

PLATINUM Documentary: Mining, Science and History

What are the top 3 uses of platinum?

Platinum is commonly known for being used in the manufacturing of jewellery but its main applications spread to catalytic converters, electrical contacts, pacemakers, drugs and magnets.

What are 3 common uses for platinum?

Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry.

Is platinum used in missiles?

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.

What is the weakness of platinum?

Platinum is unaffected by air and water, but will dissolve in hot aqua regia, in hot concentrated phosphoric and sulphuric acids, and in molten alkali.

Is platinum worth more than gold?

Price. Platinum: Despite being nearly identical in appearance, platinum is more valuable than gold. Platinum's high price point can be attributed to its rarity and density as precious metals are often priced by their weight.

Is platinum used in bombs?

Platinum is used in fertilizers and explosives as a gauze for the catalytic conversion of ammonia to nitric acid. It is also used in the fabrication of silicones for the aerospace, automotive and construction sector.

Is platinum the rarest metal on earth?

Platinum is among the rarest and most expensive of the popular precious metals. Natural platinum is fairly impure. It is always associated with small amounts of other elements (gold, copper, nickel and iron) and commonly contains the rare metals platinum, palladium, rhodium, iridium, osmium and ruthenium.

What did Native Americans use platinum for?

The early inhabitants of South America had recognised platinum and had used it for making ornaments well before the Spanish Conquest. Their techniques and ability in metal working are reviewed, based upon archaeological evidence and modern metallographic examination.

How much platinum is left in the world?

Total worldwide reserves of platinum group metals are estimated to be some 70,000 metric tons. Almost all of it, some 90 percent, is located in the Earth's crust of South Africa. Far behind it, other major countries are Russia, Zimbabwe, the United States, and Canada.

What is the hardest precious metal?

Titanium can be polished but not sized. Tungsten - Tungsten is the hardest metal in the world - four times harder than titanium. Tungsten is extremely durable.

Is platinum toxic to humans?

Platinum metal is biologically inert, whereas soluble platinum compounds (e.g., halogenated salts) encountered in occupational settings can cause platinum salt hypersensitivity with symptoms that include bronchitis and asthma after inhalational exposure and contact dermatitis after skin exposure.

What can ruin platinum?

Believe it or not, the chemicals present in everyday products like cleaning supplies, perfumes, hairsprays, etc. can be quite harsh. They can weaken the structure of your precious metal over a period of time. Also, the chlorine present in swimming pools can ruin the platinum's shine and cause discoloration.

What is stronger than platinum?

Palladium is a harder metal than platinum, which means a palladium ring is harder to scratch compared to a platinum ring.

What is the most used metal in the military?

Titanium is one of the most commonly used metals for military applications, being appreciated for its high strength-to-weight ratio and excellent corrosion resistance. The use of titanium has allowed manufacturers to create lightweight equipment, with increased durability (especially under extreme conditions).

What is the best metal for defense?

Magnesium has a reputation as a "defense metal". Magnesium is one of the lightest structural metal materials, which has the advantages of higher specific strength and specific stiffness, good damping, and cutting.

Can a bullet go through platinum?

Yes and no. If platinum is thin as a sheet of paper then no. If it is a few inches thick, then it can stop a bullet. The thickness would depend on the bullet, gun, and distance.

What is the rarest element on earth?

Astatine (At) may be the rarest naturally occurring element in the Earth's crust, but it is a member of the halogen family [fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At)] and is presumed to have characteristics similar to other Group 17 elements.

Do electric cars need platinum?

Platinum acts as an effective and durable catalyst in hydrogen-powered fuel cell electric vehicles (FCEVs). All FCEVs use a type of fuel cell known as the Polymer Electrolyte Membrane (PEM).

Where is platinum found in nature?

Platinum occurs in nature as the pure metal and also in alloys with other metals of the group, principally in the alluvial deposits of the Ural Mountains, of Columbia, and of some parts of the western United States.
