Hello friends, Today we've got facts concerning one terribly intresting material. Guess what?
Here's the hint! it's the second most abundant element on Earth, it's utilized in soda cans, creating jet planes and different vehicles and is additionally wont to build roofing sheets, providing shelter to a mess of individuals everywhere the world.
Yes, I am talking about aluminium. Here today we are going to take a glance on full history and geographics and science of Aluminium.
Facts about Aluminium
General fact
2. A Boeing-747 airplane contains 66,000 kg of the metal.
3. 8% of the Earth's crust is Aluminium.
4. The moon contains a great deal of Aluminium.
5. There are literally 100s of different Aluminium Alloys.
6. Recycling Aluminium takes just 5% of the energy used to extract fresh aluminium from ore.
7. NASA deep space researchers have harnessed Al-26 to spot supernova.
Historical facts
1. Aluminium was named after alum, which is called 'alumen' in Latin..
2. This name "aluminium" was given by Humphry Davy, an English chemist.
3. Henri-Etienne Sainte-Claire Deville, an outstanding French chemist and technologist, transferred the chemical method of aluminium creation discovered by scientists to industrial application.
4. 200 tonnes of metal were produced in 36 years (1855-1890) when the chemical method developed by Sainte-Claire Deville was applied.
5. For a long time, the metal was considered more precious than gold.
6. The metal was once so highly prized that Napoleon the Third actually served food to guests on Aluminium plates, with Aluminium cutlery.
7. Jules Verne wrote about an Aluminium space rocket in his book Journey to the Moon.
8. Ancient Greeks and Romans used Aluminium compounds both as an astringent and a fabric dye.
9. Way back in 1886, Paul Heroult and Charles Hall independently invented a way to melt Aluminium Oxide in Cryolite. The result is still used to produce Aluminium.
10. Aluminium is one of the youngest commercial metals and has only been used for around 150 years. Compared to copper, which has been around for more than 9,000 years.
Physical facts about aluminium
1. Aluminum is a shiny, silvery white-coloured metal.
2. It is light in weight but very strong.
3. The metal’s atomic weight is 26.9815386.
4. The density of aluminium is 2.7 g/mL, meaning it will sink in water but is still relatively light in weight.
5. The melting point 1,220.58 degrees Fahrenheit (660.32 degrees Celsius).
6. It boils at 4,566 degrees F (2,519 degrees Celsius).
7. Aluminium is easy to recycle & is corrosion resistant, it oxidises in the same way as Iron rusts, but oxides actually sticks to the metal and protects the surface aluminium.
8. Aluminium can be recycled over & over again with the same physical properties as the original.
9. Our bodies absorb only a small amount of the aluminium we take in with our food.
10. Aluminium can accumulate in the body, and a link with Alzheimer’s disease (only suggested but not proven).
Chemical facts about aluminium
1. Aluminum occurs as a compound, principally found in bauxite ore.
2. Aluminum combines with oxygen to form aluminum oxide when exposed to moist air.
3. When aluminum is in a powdered form it will catch fire easily if exposed to flame.
4. Hundreds of aluminum alloy compositions exist. Alloyed elements include: iron, copper, manganese, silicon, magnesium, and zinc.
5. Aluminum reacts quickly with hot water.
6. Reactive with sodium hydroxide.
7. Aluminum reacts with hot acids.
8. Aluminium reflects about 92% of visible light.
9. The Bayer process is also popular, an efficient way to extract the metal from Bauxite Ore.
10. Rubies, emeralds and sapphires have a very high crystalline Aluminium compound content.
The Mechanical Properties of Aluminum
1. Aluminum has a Young’s modulus of 10000 ksi. Compare this to copper at 17550 ksi or wood at 1595 ksi.
2. Tensile strength ultimate - 13,000 Psi
