An analysis of the history characteristics uses sources and compounds of aluminium

The following uses for aluminium are gathered from a number of sources as well as from anecdotal comments. I would be delighted to receive corrections as well as additional referenced uses. These coatings soon form a thin layer of the protective oxide and do not deteriorate as do silver coatings. These coatings are used for telescope mirrors, decorative paper, packages, toys, and in many other uses the oxide, alumina, occurs naturally as ruby, sapphire, corundum, and emery, and is used in glass making and refractories.

Chemistry in its element: End promo Chris Smith This week the chemical cause of transatlantic linguistic friction. Is it an um or an ium at the end? It turns out us Brits might have egg on our faces as well as a liberal smattering of what we call aluminium. Pure aluminium is soft.

However, alloying it with elements such as such as copper, magnesium, and zinc, dramatically boosts its strength while leaving it lightweight, obviously an asset when fighting against gravity.

And whereas iron rusts away when exposed to the elements, aluminium forms a microscopically thin oxide layer, protecting its surface from further corrosion. Happily for the transportation industry, nature has blessed us with vast quantities of aluminium. The difficulty of ripping aluminium from its oxides - for all early processes yielded only kilogram quantities at best - ensured its temporary status as a precious metal, more valuable even than gold.

In fact, an aluminium bar held pride of place alongside the Crown Jewels at the Paris Exhibition, while Napoleon is said to have reserved aluminium tableware for only his most honoured guests.

By the early s, aluminium had already supplanted copper in electrical power lines, its flexibility, light weight and low cost more than compensating for its poorer conductivity.

Aluminium alloys are a construction favourite, finding use in cladding, windows, gutters, door frames and roofing, but are just as likely to turn up inside the home: As a thin foil, aluminium is a packaging material par excellence, flexible and durable, impermeable to water, and resistant to chemical attack - in short, ideal for protecting a life-saving medication or your favourite candy bar.

There is, however, a darker side to this shiny metal. Despite its abundance in Nature, aluminium is not known to serve any useful purpose for living cells. While small amounts of aluminium are normally present in foods, we are responsible for the major sources of dietary aluminium: Swallowing over-the-counter antacids can raise intake levels by several thousand-fold.

And many of us apply aluminium-containing deodorants directly to our skin every day. While most experts remain unconvinced by the evidence, aluminium at high concentrations is a proven neurotoxin, primarily effecting bone and brain.

So, until more research is done, the jury will remain out. Now, perhaps that IS something to trouble your mind on your next long haul flight.

Next week, talking of the way the elements sound, what about this one. Say oxygen or iodine and there is no clue in the sound of the word to the nature of the element, but zinc is different - zinc, zinc, zinc, you can almost hear a set of coins falling into an old fashioned bath.

It just has to be a hard metal. In use, zinc is often hidden away, almost secretive. It stops iron rusting, sooths sunburn, keeps dandruff at bay, combines with copper to make a very familiar gold coloured alloy and keeps us alive but we hardly notice it.

This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of aluminium.

For each compound, a formal oxidation number for aluminium is given, but the usefulness of this number is limited for p -block elements in particular.

This WebElements periodic table page contains dialuminium trisulphide for the element aluminium.

It has low density, is non-toxic, has a high thermal conductivity, has excellent corrosion resistance and .
