Energy Reduction in Hall-Héroult Cells with Conventional and Special Electrodes

Abstract: Over the years, energy usage in Hall-Heroult cells has been reduced from 19–20 kWh/lb of aluminum at the turn of the century to less than 6 kWh/lb in certain operations today. This paper reviews the technology of energy usage in the process and discusses possible areas for improvement. Although improvements in technology to reduce energy usage still further are possible, results are not expected to be dramatic, except for the possible application of refractory hard metals to cathode design.

Small-Angle Scattering by Pyrolytic Graphite

Abstract: ABS>Data were obtained on small-angle scattering by pyrolytic graphite. The results indicate that small-angle scattering is due to voids in the pyrolytic graphite. The voids are nearly as numerous as the crystallites in pyrolytic graphite andd are probably pyramidal-shaped crevices having inertial distances roughly 22 by 44 A normal and parallel respectively to the mean orientation of the sheets of crystallites. The results also imply a very high density of crack nuclei in pyrolytic graphite. (P.C.H.)

Process for manufacturing clad aluminium-lithium alloys

Abstract: O A metallurgical bond at the interface between an aluminium-lithium core alloy and a metallic liner is achieved by first forming a mechanical bond along the interface betweent he core and liner, under moderated temperature and reduction conditions, and then heating the composite without simultaneous reduction to cause diffusion of the elements across the core-liner interface. The resultant metallurgical bond secures the layers together to form a composite which can be worked, shaped and fabricated by normal reduction techniques.

Electrolytic reduction cell

Abstract: The deterioration and distortion of the carbonaceous cathode lining of an aluminum reduction cell by freezing of molten cryolitic electrolyte in the lining and its subsequent reaction with sodium intercalated in the carbonaceous lining is substantially reduced by incorporating a composite strata comprised of at least one layer of a high temperature material which is capable of being wetted by molten glass and a layer of ground glass, e.g., cullet, between the carbonaceous lining and an insulating layer of refractory material.

Magnesium aluminate spinel bond for refractory brick

Abstract: A magnesium aluminate spinel-bonded refractory can be formed which does not exhibit undue expansion (due to the reaction of magnesia and alumina to form magnesium aluminate spinel) between the raw, compacted state and the fired, ceramically bonded state when fired to a temperature of 1400° C if a very finely divided alumina with dense particles is used. More specifically, the alumina used has an average particle size of less than 5, preferably less than 2, microns, and a specific surface of less than 30 m 2 /g, preferably about 5 m 2 /g (i.e., the small crystallites or particles are dense and do not have a high surface area, as do finely divided active aluminas).
