One of the earths, consisting of two parts of aluminium and three of oxygen, Al2O3.
Except in a few sections, this impurity in the boiler water is not troublesome.
A white, powdery substance produced from bauxite by a chemical process during which aluminum oxide is extracted from the ore. Between four and five tonnes of bauxite are required to produce about two tonnes of alumina, which yield one tonne of aluminum.
Refined form of aluminum oxide, pressed in molds and fired to produce a ceramic insulator useful as a substrate for hybrid integrated circuits.
an adsorbent sometimes used in adsorption chromatography. Aluminum oxide (Al2O3) is a porous adsorbent that is available with a slightly basic surface. For this reason, it can have advantages over silica, which is considered to have an acidic surface.
Aluminium oxide (Al2O3). A major compoment of pottery clays, present in amounts of c.10-40 weight per cent. The higher the alumina content, the more refractory (or difficult to melt) a clay body tends to be. It can be present in glazes, due to reaction with the body during firing, as well as in raw materials such as clay and feldspar.
any of various forms of aluminum oxide occurring naturally as corundum
Aluminium oxide (Al ), a ceramic material often used for substrates, or in ceramic bottom construction packages. Most alumina substrates contain 90-99% aluminium oxide.
Alumina: A chemical compound (Aluminium Oxide) which is a ceramic used in powder form and sprayed normally via the Plasma Spray Process
Synthetic aluminium oxide used in its crystalline form for abrasives in grinding wheels and "sandpaper" etc. Natural forms of this compound include emery, corundum, sapphire and ruby. Ruby is red because it contains chromium as an "impurity" hence the term artificial ruby used for pink grinding wheels.The term artificial sapphire is used for some "ceramic" sharpening stones. Trade names for alumina abrasive include aloxite and alundum.
Aluminium oxide (Al2 O3), a mineral used to produce primary aluminium. Alumina is extracted from bauxites by the Bayer method and the sintered Bayer method. The extraction of alumina from nepheline is by acid digestion and is produced as a by-product.
BODY: A ceramic body produced by adding quantities of Alumina Oxide to the clay recipe. The result is a whiter, stronger ceramic body.
In other words, aluminum oxide.
The native form of aluminum oxide occurring as corundum or in hydrated forms as a powder or crystalline substance.
Aluminum oxide produced from bauxite by a complicated chemical process. It is a white powdery material that looks like granulated sugar. Alumina is an intermediate step in the produciton of aluminum from bauxite.
(Al O) A major ingredient found in all clays and glazes. It is the chief oxide in the neutral group (RO) and imparts greater strength and higher firing temperatures to the body and glaze. When added to a glaze, it will assist in the formation of mat textures.
An oxide of aluminum.
The chemical compound aluminum oxide that is widely distributed in nature and occurs combined with silica and other minerals in clays, feldspars and micas, and in almost pure form in corundum. It is the major component of bauxite and is used in the production of aluminum metal.
Common name for any one of several forms of aluminum oxide (Al2O3) used in aluminum production, abrasives, ceramics, and electrical insulation.
A ceramic material made of aluminum oxide. Alumina is often used as a substrate, or underlying layer, for experiments. Alumina can be mixed with various amounts of titania (titanium dioxide) to change its properties as a substrate.
Another term for aluminum oxide
The compound of aluminum and oxygen Al2O3 that is the most common material used in ceramic PIM.
an oxide of aluminium
Aluminum Oxide, Al2O3. Exists in a variety of forms, many with high surface areas. Aluminas are very important catalyst supports and catalyst components
Aluminum Oxide, a material often used for substrates.
Aluminium oxide. It is used to bed bone china in the biscuit firing. A fine white powder with a high fusing temperature.
Aluminium oxide (commonly used to make CFFs and the filtering component of DBFs).
A compound of aluminum oxide obtained from bauxite during the production of aluminum.
(also called aluminum oxide). A compound of two parts aluminum and three parts oxygen which occurs naturally as corundum. Alumina is the base of aluminous salts, a constituent of feldspars, micas, etc., and the characterizing ingredient of common clay, in which it exists as an impure silicate with water, resulting from the erosion of other aluminous mineral s. In a hydrated form it is bauxite. Alumina is used in aluminum production and in abrasives, refractories, ceramics, and electrical insulation.
