Q:who discovered aluminum and what year did they do it?
They didnt discover it they created it its an alloy! Charles Martin Hall invented the aluminum manufacturing process Although aluminum is the most abundant metal in the earth's crust, it is never found free in nature. All of the earth's aluminum has combined with other elements to form compounds. Two of the most common compounds are alum, such as potassium aluminum sulfate (KAl(SO4)2·12H2O), and aluminum oxide (Al2O3). About 8.2% of the earth's crust is composed of aluminum. Scientists suspected than an unknown metal existed in alum as early as 1787, but they did not have a way to extract it until 1825. Hans Christian Oersted, a Danish chemist, was the first to produce tiny amounts of aluminum. Two years later, Friedrich Wöhler, a German chemist, developed a different way to obtain aluminum. By 1845, he was able to produce samples large enough to determine some of aluminum's basic properties. Wöhler's method was improved in 1854 by Henri Étienne Sainte-Claire Deville, a French chemist. Deville's process allowed for the commercial production of aluminum. As a result, the price of aluminum dropped from around $1200 per kilogram in 1852 to around $40 per kilogram in 1859. Unfortunately, aluminum remained too expensive to be widely used.
Q:What's up with aluminum foil?
Aluminum foil in the oven will quickly reach whatever temperature the oven is at. The reason it's cool when you take it out is that it equally quickly comes back to room temperature outside the oven. This is because the foil is very thin, so it has a lot of surface area, relative to its thermal mass, to exchange heat with its environment. In the microwave oven, microwave radiation makes electric current flow in the aluminum, causing it to overheat.
Q:What's good for antirust aluminium coil?
We are Ji'nan excellent Aluminum Co., Ltd., anti rust aluminum roll, now domestic generally use 3003 material, the price is now 19500 yuan / ton.3003 aluminum coil for AL-Mn alloy, is the most widely used of a rust resistant aluminum, density is 2.73.
Q:Less energy ~ Aluminum metal vs the ore?
in order to extract the raw aluminum, you have to heat everything and melt it first, then remove the stuff that precipitates out as it cools or forms via chemical reaction with catalysts you introduce. With aluminum cans, you don't have to raise the temperature much above the melting point of aluminum, since it's already the substance in the can with the highest melting point. With aluminum ore, there can be anything in the ore with pretty much any melting point. In particular, if the ore contains an alloy of aluminum and a metal with a higher melting point than aluminum, then rest assured, you will have to raise the temperature of the ore above the melting point of aluminum in order to melt that alloy, In any case, because the maximum required temperature of the smelter needed to melt used aluminum cans is necessarily lower than the maximum temperature required to work with the ore, less energy is required to get aluminum from used cans than from ore.
Q:What is the chemical formula of aluminum reacting with oxygen?
You are right about aluminum having 3 valence electrons, but oxygen has 6. Oxygen wants two more to get to 8. So the ions are Al +3 and O-2. The formula is Al2O3
Q:Why the aluminum sheet crack after?
Maybe the crack existed during welding but you didn’t notice. And then it expands and becomes obvious when acted on by external force in circling process. The reason may be the welding craft. Besides, I suggest more comprehensive tests after welding, such as penetrant test.
Q:Can the 5-10cm thick paper sleeve inside the scrapped aluminum coil be sliced? Now we use knife which is much troublesome.
You can use Long Men Rolling Mill to slice directly.
Q:Aluminum foil ice cooler insulation, inside or outside?
It's perfect if you are just starting out or if you're a seasoned carpenter. you will like it for sure ! It has almost 20.000 woodworking plans and you have a CAD/DWG software to view and edit the plans. You have step-by-step instructions with photos and high quality blueprints and schematics. If you are a beginner this is the easiest way to start your woodworking projects, and if you already have experience you can anyway find a lot of interesting ideas!
Q:Test for nitrates - Reduction by aluminium?
Aluminum is an active metal and wants to be ionized. Al -- Al(3+) + 3e(-) ın basic media, tetrahydroxoaluminate complex will be formed: Al(3+) + 4OH(-) -- Al(OH)4(-) ======================================... Al + 4OH(-) -- Al(OH)4(-) + 3e(-) Nitrate is reduced to ammonia in basic media, ammonium in acidic media: N(5+) + 8e(-) -- N(3-) NO3(-) + 8e(-) + 10H(+) -- NH4(+) + 3H2O in basic media, we add base (OH-) to both sides: NO3(-) + 8e(-) + 11OH(-) + 10H(+) -- NH4(+) + 3H2O + 11OH(-) NO3(-) + 8e(-) + OH(-) + 10H2O --- NH3 + 4H2O + 10OH(-) ======================================... NO3(-) + 8e(-)+ 6H2O -- NH3 + 9OH(-) Now, to the balancing of these two redox half reactions: Al + 4OH(-) -- Al(OH)4(-) + 3e(-) NO3(-) + 8e(-)+ 6H2O -- NH3 + 9OH(-) ============================= 8Al + 32OH(-) -- 8Al(OH)4(-) + 24e(-) 3NO3(-) + 24e(-) + 18H2O -- 3NH3 + 27OH(-) ================================== 8Al + 3NO3(-) + 32OH(-) + 18H2O -- 8Al(OH)4(-) + 3NH3 + 27OH(-) //////////////////////////////////////... 8Al + 3NO3(-) + 5OH(-) + 18H2O -- 8Al(OH)4(-) + 3NH3 Hope this helps.
Q:How do you electropolish 3003 aluminum?
Aluminium needs deoxidizing also called as desmutting after electropolishing. This is done in a hot chromic acid bath for nearly for 5 minutes.
