The material in which Shechtman discovered these quasicrystals was a mixture of manganese and aluminum. The winner of the prize, materials scientist Dan Shechtman of the Technion-Israel Institute of Technology, discovered quasicrystals, molecular structures of non-repeating patterns. Perhaps aluminum's most famous appearance on the recent research scene was in 2011, when it played a role in the Nobel Prize in Chemistry. Trippy: About 75 percent of all aluminum ever made is still in use, thanks to recycling, according to the Aluminum Association.According to the Aluminum Association, an aluminum can takes as little as 60 days to return as a new can after recycling. That can of Coke may not have been off the shelf for long.The aluminum cap initially served as the apex of the monument's lightning rod, though it had to be augmented with copper rods when it became clear that the cap alone could not prevent damage, according to a 1995 article in the Journal of the Minerals, Metals and Materials Society. The top of the Washington Monument is capped with an 8.9-inch (22.6 centimeters) aluminum pyramid.As of 2012, about 55 percent of aluminum drink cans made it into the recycling bin. Recycle! Recycling aluminum takes only 5 percent of the energy needed to extract new aluminum from ore, according to the EPA.The reaction is a demonstration of how reactive aluminum can really be.

Aluminum powder plus iodine plus a few drops of water create quite a display: Clouds of toxic purple iodine vapor and then sudden flame. Don't try this at home (unless you have a fume hood).

A single Boeing-747 contains 147,000 pounds (more than 66,000 kilograms) of aluminum, according to Chemicool.Another 1.7 million tons went toward appliances, vehicle parts and other durable goods. Environmental Protection Agency (EPA), 1.9 million tons of aluminum were produced for containers and packaging alone. Aluminum is plentiful: In 2012, according to the U.S.Using these Al-26 fingerprints, the scientists estimated that a supernova occurs every 50 years, on average, in the Milky Way galaxy, and that every year, seven new stars are born. In that study, NASA researchers used detectable bursts of Al-26 to pinpoint supernovas, or star explosions. This isotope is found in star-forming regions in the galaxy, according to a January 2006 study in the journal Nature. But Al-26, aluminum's longest-lasting radioactive isotope, has a half-life of about 730,000 years. The Hall-Heroult process is still used to produce aluminum today, along with the Bayer process, which extracts aluminum from bauxite ore, according to the ACS.Īluminum's only stable form is Al-27, and most isotopes have half-lives of mere milliseconds, meaning they are gone in less than a blink of an eye. Napoleon III also reportedly had an aluminum rattle made for his son, according to a 1911 article in Good Housekeeping Magazine.įinally, in 1886, a French engineer named Paul Heroult and an Oberlin chemistry graduate named Charles Hall independently invented a process in which aluminum oxide is melted in cryolite (sodium aluminum fluoride) and subjected to an electric current, according to the American Chemical Society. For decades, aluminum was more highly prized than gold: Napoleon III, the first president of the French Second Republic beginning in 1848, proudly served his most honored guests using aluminum plates and cutlery, because it was such a rare metal, according to The Aluminum Association. Later scientists refined the process for wresting aluminum for alum, but were unable to bring the price down to practical levels. It isn't found in pure form in nature, however in the Earth's crust, aluminum occurs most frequently as a compound called alum (potassium aluminum sulfate).ĭanish chemist Hans Christian Oersted first managed to extract aluminum from alum in 1825, according to the Thomas Jefferson National Accelerator Facility. Hsu of the Massachusetts Institute of Technology. Most common isotopes: Al-27 (stable) and Al-26 (radioactive half-life 730,000 years)Īluminum forms in stars in a fusion reaction in which magnesium picks up an extra proton, according to Chemicool, a chemistry website created by David D.Number of isotopes (atoms of the same element with a different number of neutrons): 22, one stable.Boiling Point: 4,566 degrees F (2,519 degrees C).Melting Point: 1,220.58 degrees Fahrenheit (660.32 degrees Celsius).Density: 2.70 grams per cubic centimeter.
