Aluminium fluorosilicate (Al2(SiF6)3) is used in the production of synthetic gemstones, glass and ceramic.

The melting point of aluminium, , is typically reached within minutes of the start of a fire.

Hydroelectric power generation supplies most of the country apos s electricity consumption requirements, and there is an aluminium plant with an annual capacity of 500,000 tons (15 per cent of the total aluminium capacity of the former Soviet Union).

For this reason, approximately 31 of all aluminium produced in the United States comes from recycled scrap.

Thus cast iron frying pans and cookware did not become possible in Europe until 3000 years after the introduction of iron smelting.

Aluminium sulfate (Al2(SO4)3 (H2O)18) is produced on the annual scale of several billions of kilograms.

In geology, beryl is a mineral composed of beryllium aluminium cyclosilicate with the chemical formula Be3Al2(SiO3)6.

Examples for material systems used are gallium arsenide (GaAs) and aluminium gallium arsenide (AlGaAs) or other compound semiconductors.

Steel is completely recyclable, and its production requires relatively small amounts of energy, compared, for instance, to aluminium.

But about two centuries before David, the Hittites had discovered the secret of smelting and processing of iron, and, slowly, that skill spread.

Though slightly more expensive than traditional steel or aluminium alternatives, these titanium products can be significantly lighter without compromising strength.

This will usually be aluminium chlorohydrade and aluminium zirconium trichlorohdrex, either of which will react with the electrolytes in your sweat to create a thick gel that effectively blocks the top of your sweat glands, and which also acts astringently to cause your pores to contract.

41. The declining importance of such agreements contrasts sharply with the recent successes of coffee and aluminium producers in boosting prices.

Because, of course, they don't actually tell you how to do it if you want to do it yourself and you don't have a smelting plant.

The third project by the Canadian company, Inco, for a new nickel mining and smelting project at Goro, South Province, resumed in early 2005, following long delays.

The concentration of aluminium in many landfills is higher than the concentration of aluminum in bauxite from which the metal is derived.

The value of exports of aluminium declined by approximately 50 per cent from 30.6 million in 1990 to 15.3 million in 1991.
