Q:Can you make aluminum oxide by electrolysis?
The way I remember it is a cathode is like a catheter because they both receive stuff and the anode is the opposite of that) So, if you break apart Al2O3 you have 2Al^3+ and 3O^2-. Al^3+ goes to the cathode to receive electrons and become a neutral metal. O^2- goes to the anode to donate electrons and become O2 gas. Hope the analogy and explanation helps!
Q:Calculate Number of Aluminium ions ?
The formula for aluminium oxide is Al2O3 Its molecular weight is 2*27+3*16= 54+48 =102 Now, 102g of Al2O3 contains 2*6.023*10^23 number of Al ions so 1g contains (2*6.023*10^23)/102 number of Al ions so 0.051g Al2O3 contain (2*6.023*10^23)/102 *0.051 number of Al ions which is equal to 6.023*10^23*10^-3 = 6.023*10^20 number of Al ions(Answer)
Q:How to Machine High Purity Aluminum machinery?
Aluminum okorder.com is a soft, silvery-white metal. In high-purity aluminum nearly all impurities have been removed. It is 99.99 percent pure and is machined like other grades of aluminum. To process aluminum for various applications, the manufacturer heats the aluminum in a smelter and then forms it into ingots (large blocks) or billets (log-shaped rods). Using rolling mills, workers machine ingots into aluminum plates, sheets or foils. Dies machine ingots or billets into extrusions or forgings.
Q:Aluminum vs. steel?
If you define stronger to be a higher yield strength, then it's about dislocation movement. Dislocations form as a material begins to deform. As more deformation occurs, dislocations begin to move. Since steel is iron with impurities (namely carbon), these impurities impede dislocation movement. Aluminum, in pure form, does not have anything to impede dislocation movement except for the grain boundaries of the microstructure, which the steel also has if the microstructures are identical. If you define stronger as in ultimate tensile strength, then it becomes an issue of bond strength. Basically how tightly iron atoms bond to one another versus aluminum atoms. There are some quantum mechanical considerations at this point, but I won't get into those details.
Q:Aluminum, A good bottle material to drink from?
Not really. Al in your diet is believed to be a cause of Alzheimer's disease. And putting acids (like fruit juice) in a bottle would definitely corrode the metal somewhat; water is slower but there is a taste that means that some Al is going in. Thus many (most/all?) Al bottles are lined in plastic and have plastic closures. Stainless steel with a stainless steel closure are a much better choice than Al. But they are harder to find and often more expensive. Stainless steel with polyprop. closures but not plastic lined are easier to find (but less durable; I am forever breaking off the poly tabs). Of course Al bottles are better than plastic bottles.
Q:What keeps things colder- plastic wrap or aluminum foil?
Aluminum foil. It is thicker, and metal retains heat/cold longer than the thin film of plastic would. I actually use both when I freeze things like lasagna...I use a layer of plastic wrap on it first, then a layer of foil over the top. It creates an extra (albeit fine) layer of insulation.
Q:how to produce aluminium sheet circle?
As for the process, you can use punch.. as for professional machines, for example, stationary press in open type, mechanical press/ single-point press. The material you say is neither big nor small, blanking…(cutting them into sheet circle you want) you can add an uncoiling if it’s coil stock: open-type inclinable press, four-point press,ect. It’s not certainly accurate) punch, oil press, double , four-column hydraulic (oil) press,etc. it needs about 315T,(estimated value, closed type single, blank material cutting (cutting into square ) 2, it contains sheet metal forming technology, crank press: 1: straight side two : 1, but the components you said is simple, only two steps.
Q:what kind of aluminum sheet is suitable for aluminum alloy double-edged saw?
saw web size depends on the thickness and height of sectional material,equipment compatibility and permitted installed saw web size .
Q:Has anyone heard of Lydney Aluminum?
Lydney Aluminum, I don't think that I have heard of them in the boating industry. T.
Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
hardware
