2024年12月21日 · British chemist Sir Humphry Davy had prepared (1809) an iron-aluminum alloy by electrolyzing fused alumina (aluminum oxide) and had already named the element aluminum; the word later was modified to aluminium in England and some other European countries.

Aluminum is the second most abundant metallic element in the Earth's crust after silicon, yet it is a comparatively new industrial metal that has been produced in commercial quantities for just over 100 years.

Element Aluminium (Al), Group 13, Atomic Number 13, p-block, Mass 26.982. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images.

Aluminium, or Aluminum in American spelling, is an ancient metal and has a diverse range of uses. It was discovered in 1824 and its light weight, high electrical conductivity and high resistant to corrosion has make it an industrially attractive metal.

2014年9月29日 · Properties, uses and sources of the element aluminum. Also known as aluminium, the name was changed by the American Chemical Society in 1925.

2009年6月16日 · Aluminium citrate is more soluble than many other aluminium compounds and is likely to be more bioavailable from drinking-water than from food. The Committee concluded that the NOAEL of 30 mg/kg bw per day was an appropriate basis for establishing a PTWI for aluminium compounds.

Aluminum naturally produces a thin oxide covering that protects the metal from further interaction with the environment. Aluminum alloys are less corrosion resistant than pure Aluminium except for marine magnesium-aluminum alloys. Aluminum is a good conductor of heat and electricity.

The element was known in prehistoric times. In 1825, the Danish physicist, Hans Christian Oersted, isolated impure aluminium. The pure metal was first isolated by the German chemist Friedrich Wöhler in 1827.

In complex ions or molecules, Aluminium often adopts an octahedral geometry, with six atoms, ions, or molecules surrounding the central Aluminium atom. However, tetracoordinated and pentacoordinated Aluminium complexes also exist.

2023年4月15日 · Aluminium is the most prevalent metallic element in the Earth’s crust (8.23% by mass) and the third most plentiful element overall (after oxygen and silicon). Aluminium is found in a wide range of silicates in the Earth’s crust. The Earth’s mantle, on the other hand, is only 2.38% aluminum by mass.
