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.

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

1949 Sumitomo Chemical takes over the aluminum business of Sumitomo Aluminium Smelting Co., starting the integrated production of aluminum from alumina.

This compound is used as flux in the smelting of secondary aluminium, to reduce or remove the magnesium content of the melt.

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

Aluminium ammonium sulfate, which is also called ammonium alum, (NH4)Al(SO4)2 12H2O, is used as a mordant and in leather tanning.

Waste contains many resources with high value, the most notable of which are non ferrous metals such as aluminium cans and scrap metal.

A Federation level agreement on the long disputed ownership of the nationally vital firm Aluminium Mostar opened the way for its major expansion.

Aluminium phosphate (AlPO4) is used in the manufacture of glass and ceramic, pulp and paper products, cosmetics, paints and varnishes and in making dental cement.

The concrete is cast around a plastic, steel or aluminium curved duct, to follow the area where otherwise tension would occur in the concrete element.

List of producing countries This is a list of countries by aluminium oxide in 2006 mostly based on British Geological Survey accessed in June 2008.

Glass for flat glass has a higher magnesium oxide and sodium oxide content than container glass, and a lower silica, calcium oxide, and aluminium oxide content.

One example of a nickel based niobium containing superalloy is Inconel 718, which consists of roughly 50 nickel, 18.6 chromium, 18.5 iron, 5 niobium, 3.1 molybdenum, 0.9 titanium, and 0.4 aluminium.

With the exception of scrap iron and copper, aluminium and mineral coal waste, the export of all local goods and commodities is permitted for trade purposes, subject to the following requirements

In late 2004, the Mexican company CCL Container S.A. de C.V. de México, from which Cuba had ordered lithographed aluminium tubes for packaging cigars, was bought by a United States company.

I'm looking at single surface structures and how they flow how they stretch and flow. It's based on furniture typologies, but that's not the end motivation. It's made from aluminum, as opposed to aluminium, and it's grown.

Heavy metals (aluminium, chromium, arsenic, and copper) dissolved in the water as a result of coal burning were deemed to be at acceptable levels, but metals in sediment and mercury in larger pike were found to be excessive.

Studies of meteorites suggests that radioactive isotopes such as aluminium 26 with a half life of 7.17 105 years, and potassium 40 with a half life of 1.250 109 years, isotopes mainly produced in supernovae, were much more common.

In addition, Moseley predicted the two more undiscovered elements, those with the atomic numbers 72 and 75, and gave very strong evidence that there were no other gaps in the Periodic Table between the elements aluminium (atomic number 13) and gold (atomic number 79).

Reducing the use of steel by inventing an aluminium engine increasing space by moving the wheels to the edge of the chassis and relying on a modular design that enables the car to be assembled from kits proved conclusively that you could do more with less.

On 28 December 2004, the company Maquimport requested a quote for 47 products from the United States subsidiary Rockwell Automation Power Systems, based in Canada. The products in question were intended primarily to meet the demand for spare parts at Holguín's aluminium container production plant (ENVAL).
