Aluminum trioxide

Chemically, all clays are composed of oxides of silicon, aluminum, and hydrogen - namely, silicon dioxide, aluminum trioxide, and water in a weight proportion that can be expressed by the following general formula (see Fig. 50) ... 

Picking the fruit requires two steps. In step three, the triethyl aluminum product is oxidized to an aluminum trioxide alkane (trialkoxide). by adding dry air at about 100°F above atmospheric pressure. This is done with the rriethyl aluminum product mixed in a solvent to avoid local overheating and decrease the viscosity of the solution. The solvents and by-products are removed overhead by distillation.

Michael addition of 1 to dimethyl acetylene dicarboxylate in the presence of sodium methoxide, potassium fluoride, or aluminum trioxide gave 435 (R = Me) via an intermolecular cyclocondensation (89MI87). Regioselective cycloaddition of propargylic alcohol and dimedone in the presence of thiolate-bridged diruthenium complex afforded the tetrahydrobenzo[fr]pyran 451 (04JOC3408).

The use of chemical vapor deposition (CVD) and physical vapor deposition (PVD) for forming coatings of carbides, boride, nitrides, and oxides has increased. The CVD method has been developed the furthest for the deposition of TiC, titanium nitride (TiN), chromium carbide (CrC), WC, and aluminum trioxide (AI2O3) (Simon and Thoma 1985). 

Perovskite A class of crystalline materials that often has the same formula and crystal structure. Two perovskites, strontium titanium trioxide and lanthanum aluminum trioxide, were central in the discovery of high-temperature superconductivity. 

Another approach to removing the reaction product is a filter/precipitator system, as shown in Fig. 38.42. The aluminate concentration is controlled by pumping the electrolyte out of the cell stack and through the filter/precipitator. The filter promotes the growth of the aluminum trioxide and regeneration of KOH as follows ... 

Light-colored fillers do play an important role in NBR compounding, especially in the roller business. The main types of non-black fillers used with nitrile rubber are silica, silicate, clay, talc, and calcium carbonate. In addition there are many specialty light-colored fillers such as diatomaceous earth, barium sulfate, titanium dioxide, aluminum trioxide, antimony trioxide, magnesium hydroxide, and zinc oxide to name a few.
