In today’s world, it is impossible to do without aluminum. Alloys based on this metal are so widely used in a variety of industries that they have become truly indispensable. Fortunately, its reserves in the Earth are still very large, and in the next thousand years, humanity is unlikely to have to worry about its deficit. However, who knows, perhaps in the future aluminum will gradually be replaced by other materials?
Facts about aluminum
- Of all the chemical elements on Earth, only silicon and oxygen are more abundant than aluminum.
- The metal is almost never found in its pure form, as it easily combines with other substances. Pure aluminum in minute amounts was found only in the vents of volcanoes.
- For the first time pure aluminum was got in the course of an experiment in 1825. Scientific breakthrough was made by Danish scientist Hans Oersted.
- Of all metals, aluminum is the most common in the Earth’s crust.
- A few centuries ago, aluminum was worth more than gold. For example, the French Emperor Napoleon III ate from aluminum cookware.
- An ordinary aluminum drink can decays in the soil for about 80-85 years.
- The bodies of modern automobiles are often made of aluminum alloys, since reducing the weight of the car directly affects fuel economy.
- In the mid-19th century, the most expensive jewelry was made precisely from aluminum.
- Mercury easily corrodes aluminum, which is why it is forbidden to take it on board aircraft. Their hulls are made of aluminum alloys.
- Aluminum has a very high albedo. Well-polished aluminum surface reflects over 90% of the light hitting it.
- The metal became widespread around the world only after it had been produced on an industrial scale in a cost-effective way.
- Of the many isotopes of aluminum, only two are found in nature. The others can only be produced artificially.
- In terms of annual world production, aluminum is second only to iron.
- Scientists believe that 7-8% of the entire crust of our planet is made of aluminum, which is included in other metals and minerals.
- Aluminum is used to make synthetic sapphires that are virtually indistinguishable from real ones. They are heated to 2200 degrees Celsius under great pressure.
- One isotope of this metal is radioactive.
- About 30% of all drinks in the world are poured into aluminum cans. The rest are in glass, cardboard bags, and plastic bottles.
- The American Charles Hall invented a way to produce aluminum cheaply. A monument was erected to his credit, made of pure, impurity-free aluminum.
- Aluminum is present in many precious stones as an impurity.
- It burns very well. Grinded into dust, aluminum is a common additive to rocket fuel, as it helps to increase the efficiency of engines.
- In the Earth’s crust, aluminum is part of over 270 minerals.
- All ores containing aluminum only melt at a high enough temperature, which is why it took so long to learn how to isolate it.
- Australia is the world’s number one miner and producer of this metal.
- Byproducts from aluminum mining are used in the production of asphalt and concrete.
- Steel is three times denser and tougher than aluminum.
- It is also often used in fireworks to make bright white flames with lots of beautiful sparks.
