Aluminium oxide (or aluminium(III) oxide) is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium oxide. It is commonly called alumina and may also be called aloxide, aloxite, or alundum in various forms and ...
Anodic aluminum oxide, anodic aluminum oxide (AAO), or anodic alumina is a self-organized form of aluminum oxide that has a honeycomb-like structure formed by high density arrays of uniform and parallel pores. The diameter of the pores can be as low as 5 nanometers and as high as several hundred nanometers, and length can be controlled from few ...
Aluminium(I) oxide is a compound of aluminium and oxygen with the chemical formula Al 2 O. It can be prepared by heating the stable oxide Al 2 O 3 with elemental silicon at 1800 °C under vacuum .
In March 2013, Phinergy [5] released a video demonstration of an electric car using aluminium–air cells driven 330 km using a special cathode and potassium hydroxide. [6] On May 27, 2013, the Israeli channel 10 evening news broadcast showed a car with Phinergy battery in the back, claiming 2,000 kilometres (1,200 mi) range before replacement ...
This oxide layer has a voltage proof of approximately 1 to 1.5 V. [37] Therefore, aluminum electrolytic capacitors with non-solid electrolyte can continuously withstand a very small reverse voltage [38] and, for example, can be measured with an AC voltage of about 0.5 V, as specified in relevant standards.
The aluminium(I) cation reacts with hydrogen halides to form the following aluminium monohalides: [1] aluminium monofluoride (AlF) aluminium monochloride (AlCl) aluminium monobromide (AlBr) aluminium monoiodide (AlI) These compounds are only thermodynamically stable at high temperatures and low pressures in the singlet ground state.

Atomicity is the total number of atoms present in a molecule of an element. For example, each molecule of oxygen (O 2) is composed of two oxygen atoms. Therefore, the atomicity of oxygen is 2. [1] In older contexts, atomicity is sometimes equivalent to valency. Some authors also use the term to refer to the maximum number of valencies observed ...
