It is a semiconductor, so would probably be good for machinery like Silicon. Most likely it would be used for computers and lasers somehow.

Embedded aluminum roof flashing, aluminum water stops, aluminum electrical conduit, introduced aluminum powder (sometimes used to foam concrete), or embedded structural aluminum shapes may all corrode in concrete or mortar. In all cases, a reaction that forms aluminum hydroxide and hydrogen gas occurs, and may cause expansion and cracking of the concrete or mortar. The common use of calcium chloride (or other alkali compounds), and dampness of the concrete increases the reaction rate. Usually, coating the aluminum with bituminous paint, impregnated paper or felt, plastic, or an alkali-resistant coating will prevent or sharply reduce the corrosion.

One is the simple physics of collisions. Rutherford Back Scattering is used today to measure thin films. It is just bouncing balls so is not affected by chemistry.\nThe physics of elastic collisions was well defined by others. (billiard balls with balls of different masses) People used radioactive sources and understood the nature of alpha particles. So when the very thin film of gold didn't stop most of the particles, there was no surprise. The ones that did, were the surprise and the interesting/useful part of the experiment.\nNewtonian physics, elastic collisions, alpha particles, radioactive sources were available.\nThis should be a start.

I've heard of people claiming you can smelt aluminum, etc., in a microwave oven, if you use silica bricks to contain the heat. You might also need to use a graphite crucible, which will heat up but that the molten metal will not stick to. \n\nFinally, since magnesium is SO flammable (but that's why you want to smelt it, to make inconspicuous incendiary devices, right? you dirty little terrorist) you need to have a continuous stream of some non-oxidizing gas, such as nitrogen, flowing through the oven while it is in use.\n\nBottom line? Don't try this at home. You'll get yourself killed if you're lucky, burned and crippled for life if you're not. And I'm asking the yahoo people to contact the local law enforcement authorities in your area.

Try gelest.com, they manufacture a LOT of Si compounds for many applications.

Forget the potassium ions - they don't do anything. The aluminium metal dissolves in the potassium hydroxide solution, forming aluminate ions and hydrogen gas.\n\nThe ionic equation is:\n\n2Al + 2OH- + 6H2O ---> 2[Al(OH)4]- + 3H2\n\nTo explain how to get this equation, you need the ideas of half equations, and oxidation and reduction.\n\nFor example, Al + 4OH- ---> [Al(OH)4]- + 3e-\n\nand 4H2O + 4e- ----> 2H2 + 4OH-\n\nNow combine them, getting the number of electrons equal, and cancelling down some hydroxide ions.\n\nIf it's any consolation, this exercise would be beyond most A-level pupils in the UK.

Precipitation Treatment (or hardening) is a heat treatment technique to improve the strength of aluminum alloys.\n\nA typical aluminum alloy will contain mostly aluminum, but also some copper (could also contain; magnesium, silicon, zinc... but the idea is the same).\n\nThe strength of a metal is very dependent on its microscopic grain structure (microstructure), since deformation of a metal is caused by the propagation of discontinuities in the microstructure, thus grain size, crystal type, inclusions, all effect its strength.\n\nImprove the grain structure and you improve the allow. What precipitation treatment involves is first heating up the allow to a prescribed temperature - This causes all the alloy metals to completely disolve in the aluminium (and gives a randomly diffused solid structure). Next (typically) the metal is quenched (ie. for example in water to rapidly cool it) - This results in a super-saturated solution of the alloys in the aluminum. Finally, the metal is aged (volkwagen used to dump their new engine blocks out in a field for a few months) to allow time for the alloys to precipitate out of solution. The result is a nice uniform small grained microstructure where the small alloy precipitates reinforce the lattice of the aluminum.

One method is using bimetallic strips of metals that can stand very high temperature. Bimetallic strips bend when the temperature changes.

The filament of a light bulb must become hot enough to emit light without melting.  Copper, aluminim, gold and silver are all very good conductors with relatively low melting points and are not used for filaments.  Tungsten is an excellent filament material because it is a poor conductor resisting current and glows white hot without melting or losing required strength.  Tungsten eventually "boils" away and the filament weakens and has a finite life (which can be lengthened by reducing voltage with a dimmer).  Many materials including carbon can work in a light bulb because all the air (especially oxygen) is removed, otherwise the material would burn up and fail at the very high temperature.

What you are asking about is in the realm of surface science.  There are many analytical techniques and I will not try to go through all of them.  This is a good starting place: http://www.uksaf.org/tech/list.html

Its a salt of beryllium and is toxic and is mainly used to extract the beyllium from it and hence is an mineral. Beryllium is used in aerospace and defense industry as light weight structural material. Beryllium is used in nuclear weapons for similar reasons. \n\n\nBeryllium is used as an alloying agent in the production of beryllium-copper because of its ability to absorb large amounts of heat. Beryllium-copper alloys are used in a wide variety of applications because of their electrical and thermal conductivity, high strength and hardness, nonmagnetic properties, along with good corrosion and fatigue resistance. These applications include the making of spot-welding electrodes, springs, non-sparking tools and electrical contacts.\n\n\nThin sheets of beryllium foil are used with X-ray detection diagnostics to filter out visible light and allow only X-rays to be detected.\n\n\nBecause it has a low thermal neutron absorption cross section, the nuclear power industry uses this metal in nuclear reactors as a neutron reflector and moderator

its makes for versatile application of the particular element..for instance graphite allotrope of carbon can be used for pencil lead

Of course, aluminum wins as it has the lowest density.  The passivating oxide film makes aluminum non-corrosive, which is a great comfort to the metallurists and structural engineers responsible for keeping these birds in flight, rather than cracked up over an ocean.

Aluminium or aluminum is the chemical element in the periodic table that has the symbol Al and atomic number 13. It is a silvery and ductile member of the poor metal group of chemical elements. Aluminium is found primarily as the ore bauxite and is remarkable for its resistance to corrosion (due to the phenomenon of passivation) and its light weight. Aluminium is used in many industries to make millions of different products and is very important to the world economy. Structural components made from aluminium and its alloys are vital to the aerospace industry and very important in other areas of transportation and building in which light weight, durability, and strength are needed.\n\nAluminium is a soft and lightweight metal with a dull silvery appearance, due to a thin layer of oxidation that forms quickly when it is exposed to air. Aluminium is nontoxic (as the metal), non-magnetic, and non-sparking. Pure aluminium has a tensile strength of about 49 megapascals (MPa) and 400 MPa if it is formed into an alloy. Aluminium is about one-third as dense as steel or copper; is malleable, ductile, and easily machined and cast; and has excellent corrosion resistance and durability due to the protective oxide layer. Aluminium mirror finish has the highest reflectance of any metal in the 200-400 nm (UV) , and the 3000-10000 nm (far IR) regions, while in the 400-700 nm visible range it is slightly outdone by silver, and in the 700-3000 (near IR) by silver, gold and copper. It is the second most malleable metal (after gold) and the sixth most ductile. Aluminium is a good heat conductor which is why it is used to make saucepans.
