	Aluminium oxide - Wikipedia, the free encyclopedia
		Aluminium oxide is an excellent thermal and electrical insulator.
		Aluminium oxide is responsible for metallic aluminium's resistance to weathering.
		Aluminium oxide, also known as alumina, is the main component of bauxite, the principal ore of aluminium.

	Aluminium - Wikipedia, the free encyclopedia
		Aluminium is found primarily as the ore bauxite and is remarkable for its resistance to corrosion (due to the phenomenon of passivation) and its light weight.
		Aluminium is a soft and lightweight metal with a dull silvery appearance, due to a thin layer of oxidation that forms quickly when it is exposed to air.
		Aluminium was selected as the material to be used for the apex of the Washington Monument, at a time when one ounce cost twice the daily wages of a common worker in the project; aluminium was a semiprecious metal at that time.

	Aluminium oxide
		Aluminium oxide is the main component of the principal ore of aluminium (bauxite), and the main component of the gems ruby and sapphire.
		Metallic aluminium is very reactive with atmospheric oxygen, and a thin layer of aluminium oxide quickly forms on any exposed aluminium surface.
		Powdered aluminium oxide is frequently used as a medium for chromatography.

	Aluminum oxide (UK PID)
		Aluminium oxide is employed widely in the manufacture of alloys, ceramics, glass, electrical insulators and resistors.
		Aluminium oxide is used as an industrial catalyst, adsorbant, desiccant, and as a filler for paints and varnishes.
		The presumed low toxicity of inhaled aluminium oxide led in the past to its use as a prophylactic agent against silicotic lung disease in miners but this practice was abandoned in the 1970's amid concern that chronic exposure may be harmful.

	Aluminium
		Powdered aluminium and rust in the approximate ratio of 1:3 are packed in a refractory crucible with a magnesium ribbon, or a powder of magnesium and barium peroxide, to ignite it.
		Aluminium can be protected by a thick layer of oxide made by electrolysis, a process called "anodizing." The surface is first thoroughly cleaned and degreased in trichloroethylene, or by electrolysis, where the aluminium is the cathode and the grease driven off by the evolved hydrogen.
		Aluminium sulphate is found in nature as the rare mineral Kalinite, which is soluble in water, so it is found only near volcanoes and such places where it is make by the action of sulphuric acid on clays, such as on Lipari, near Vesuvius, and a few places in Germany and South America.

	Magnesium-aluminium oxide (spinel)
		Therefore, in the Jena laboratory, a systematic study of the infrared properties of Mg-Al oxides of both synthetic and natural origin was performed in order to derive the optical constants of these materials.
		This led to the discovery of two accompanying features in the astronomical spectra at larger wavelengths, thereby strongly supporting the idea of spinel condensates in AGB star outflows (see Fig.
		13] and condensation studies of oxide grains in low-presure oxygen-rich atmospheres.

		Normally the concentration of abrasive in a slurry may be reduced by at least 25% when changing to Logitech Calcined Aluminium Oxide Abrasive Powder from regular alumina abrasives.
		In each of the instances noted, surface finish will be relatively unchanged, due to the lower "apparent" particle size of the Calcined Aluminium Oxide, resulting from their flatter shape when compared to conventional regular aluminium oxide abrasive powders.

	dissolving aluminium oxide in cryolite
		The Al3+ ions from the aluminium oxide are 'solvated' by the molten AlF4- ions from the molten cryolite and carried into solution.
		Similarly the oxide ions are carried into soolution solvated by the sodium ions of the cryolite.
		If the energy is favourable (and in this case it must be) ions will dissolve by forming bonds with the solvent particles - in this case Na+ and AlF4- ions.
