Aluminum, reduction

The principal use of AIF. is as a makeup ingredient in the molten cryoflte, Na.. AIF AI2O2, bath used in aluminum reduction cells in the HaH-Haroult process and in the electrolytic process for refining of aluminum metal in the Hoopes cell. A typical composition of the molten salt bath is 80—85%... [Pg.140]

Other methods iaclude hydrogen reduction of TiCl to TiCl and TiCl2 reduction above the melting poiat of titanium metal with sodium, which presents a container problem plasma reduction, ia which titanium is collected as a powder, and ionized and vaporized titanium combine with chlorine gas to reform TiCl2 on cool-down and aluminum reduction, which reduces TiCl to lower chlorides (19,20). [Pg.100]

Tungsten oxytrichlofide [14249-98-0], WOCl, a green soHd, is prepared by the aluminum reduction of WOCl in a sealed tube at 100—140°C (14). [Pg.287]

Materials made of siHcon nitride, siHcon oxynitride, or sialon-bonded siHcon carbide have high thermal shock and corrosion resistance and may be used for pump parts, acid spray nozzles, and in aluminum reduction ceUs (156—159). A very porous siHcon carbide foam has been considered for surface combustion burner plates and filter media. It can also be used as a substrate carrying materials such as boron nitride as planar diffusion source for semiconductor doping appHcations. [Pg.469]

The third category for interactions is high dose (III). The effects produced by this level of interaction can be seen by the casual observer. The result of high-dose exposure is destruction or severe injury of the forest system. High-dose conditions are almost always associated with point source emissions. The pollutants most often involved are SO2 and hydrogen fluoride. Historically, the most harmful sources of pollution for surrounding forest ecosystems have been smelters and aluminum reduction plants. [Pg.120]

BLP (Buoyant Line and Point Source Dispersion Model) is a Gaussian plume dispersion model associated witli aluminum reduction plants. [Pg.384]

The aluminum reduction of a refractory metal oxide invariably yields a metal product containing significant amounts of residual aluminum and oxygen, represented usually as a metal-aluminum-oxygen alloy. When the metal contains aluminum in addition to oxygen, a number of reactions can occur during pyrovacuum treatments. These are ... [Pg.449]

In a study of 22,010 US male aluminum reduction workers with over 5 years employment in the industry, there was a slight positive association with lung cancer [standardized mortality ratio (SMR) = 121], which was somewhat stronger in Soderherg workers (SMR = 162). There was a slight, hut not statistically significant, excess of leukemia (SMR= 170) and lymphoma (SMR = 125) in potroom workers. [Pg.179]
