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

Aluminium atoms are arranged in a face centered cubic (fcc) structure.

Aluminium borate (Al2O3 B2O3) is used in the production of glass and ceramics.

It makes up about 8 by weight of the Earth's solid surface.

The great majority of this material is converted to metallic aluminium.

Aluminium(I) AlF, AlCl and AlBr exist in the gaseous phase when the trihalide is heated with aluminium.

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

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

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

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

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.

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

This high temperature heat treatment breaks the aluminum oxygen bonds and the aluminum atom is expelled from the zeolite framework.

The method is based on the use of well defined porous templates, such as porous aluminum or silicon.

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

Héroult's process was in production by 1889 in Switzerland at Aluminium Industrie, now Alcan, and at British Aluminium, now Luxfer Group and Alcoa, by 1896 in Scotland.

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

The engine block is cast iron instead of aluminum for up to 50 faster warm up, at the expense of additional weight.

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.

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.

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

If you are interested in improving your own life by recycling, why not try making this shopping bag out of repurposed aluminum coffee bags, like this Finnish woman?

It has a transition economy that is dependent on aluminum and cotton production, its economy is the 126th largest in the world in terms of purchasing power and 136th largest in terms of nominal GDP.

The quality of these materials for recycling and reprocessing purposes is not as high as initially recycled materials, however materials such as aluminum and steel are usually excluded from this.

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.

In moments of war there's great technological innovation, and in the world you have to do without well, during the Second World War, you had to do without steel, you had to do without aluminum.

In the field of health and medicine, the Committee noted that a filter made of nanoaluminium oxide fibres could be used to remove impurities from drinking water in areas on Earth where water was scarce and potentially contaminated.

Possibly the energy released by the decay of 60Fe contributed, together with the energy released by decay of the radionuclide 26Al, to the remelting and differentiation of asteroids after their formation 4.6 billion years ago.

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).

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.

The right to equal remuneration, including benefits, and to equal treatment in respect of work of equal value, as well as equality of treatment in the evaluation of the quality of work.

In absolute numbers the Greek military budget ranked 28th in the world in 2005.

The enrolment rate is 98 per cent for men and 96 per cent for women for elementary education, 56.3 per cent for men and 57.5 per cent for women for secondary education, 18.4 per cent for men and 21.3 per cent for women in higher education.

Russell died of influenza on 2 February 1970 at his home, Plas Penrhyn, in Penrhyndeudraeth, Merionethshire, Wales.
