In substitutional metallic solid solutions and in liquid alloys the experimental data have been described by Epstein and Paskin (1967) in terms of a predominant frictional force which leads to the accumulation of one species towards the anode. The relative movement of metallic ion cores in an alloy phase is related to the scattering cross-section for the conduction electrons, which in turn can be correlated with the relative resistance of the pure metals. Thus iron, which has a higher specific resistance than copper, will accumulate towards the anode in a Cu-Fe alloy. Similarly in a germanium-lithium alloy, the solute lithium atoms accumulate towards the cathode. In liquid alloys the same qualitative effect is observed, thus magnesium accumulates near the cathode in solution in bismuth, while uranium, which is in a higher Group of the Periodic Table than bismuth, accumulated near the anode in the same solvent.

Other common anode materials for thermal batteries are lithium alloys, such as Li/Al and Li/B, lithium metal in a porous nickel or iron matrix, magnesium and calcium. Alternative cathode constituents include CaCr04 and the oxides of copper, iron or vanadium. Other electrolytes used are binary KBr-LiBr mixtures, ternary LiF-LiCl-LiBr mixtures and, more generally, all lithium halide systems, which are used particularly to prevent electrolyte composition changes and freezing out at high rates when lithium-based anodes are employed. 

The last type of reserve cell is the thermally activated cell, lhe older designs use calcium or magnesium anodes newer types use lithium alloys as anodes. 

CARBONIC ACID GAS (124-38-9) COj Reacts violently with strong bases and alkali metals. Violent ignition or explosive reaction may occur when dusts of chemically active metals such as aluminum, chromium, lithium, manganese, magnesium, potassium, sodium, titanium, zirconiiun, and some magnesium-aluminum alloys are suspended and heated in carbon dioxide. The presence of strong oxidizers will increase the potential for ignition or explosions of metal dusts. 

Lithium is used to a limited extent in industry in various alloys. It increases the tensile strength and resistance of magnesium alloys to corrosi on a calcium-lithium alloy is used in purifying copper for high conductivity work. Addition of about o-1 per cent of lithium to aluminium-zinc alloys enhances their tensile strength. 

Metalhc hthium has a variety of uses. It is used as an anode material in batteries and as a heat transfer agent. Magnesium-hthium alloys are used to produce armor plate and aerospace materials, while aluminum-hthium alloys find applications in the aircraft industry. Lithium is also used to produce chemical reagents such as LiAlH4 (a reducing agent) and n-butyhthium (a strong base).

The electrons for the radical anions are injected by the cathode, consisting of a metal with a low work function. Usually, calcium, a coevaporated magnesium-silver alloy with a Mg Ag ratio of 10 1, or aluminum can be used. The corresponding work functions are 2.9 eV, 3.7 eV, and 4.3 eV, respectively. The injection of the electrons can be facilitated by an additional layer of lithium fluoride [40]. Several mechanisms have been proposed to explain the electron injection improvement [41,42]. The most plausible mechanism is the dissociation of LiF toward metalHc hthium, which acts as a redox dopant for the electron-transport layer. From the cathode the electrons are then transported through the electron- transport layer on the LUMO level via hopping transport, which is in principle a mutual solid-state redox reaction. 

Because unalloyed magnesium is not used extensively for structural applications, it is the corrosion resistance of magnesium alloys that is of primary interest. To enhance strength and resistance to corrosion, magnesium is alloyed with aluminum, lithium, zinc, rhenium, thorium, and silver, with minor additions of cerium, manganese, and zirconium sometimes being used as well. 

The basic driving forces for materials selection for aerospace optical systems are weight, stiffness, and stability. These systems, whether cameras, telescopes, spectrometers, or heliographs, have used and helped to drive the state-of-the-art of beryllium, beryllium-aluminum, magnesium, magnesium-lithium, other experimental alloys, and also materials in the composites field. The weight and stiffness criteria are self-explanatory, but the stability needs require some further explanation before we examine the use of composites in these systems.

Tin hydride has been made by the reaction of hydrochloric acid with magnesium-tin alloy (1) or metallic tin (2) by reduction of stannous salts electrolytically (3), by metals (4, 5), or sodium borohydride (6) and by reduction of stannic chloride by atomic hydrogen (7) or metals (S). Perhaps the most practical method involves the reduction of stannic chloride with lithium aluminum hydride under nitrogen (9, 10, 11) containii 0 1% oxygen 12) at — 70° C. The presence of oxygen inhibits the decomposition, which ordinarily occurs at room temperature. This inhibition is at least partially due to the fact that metallic tin is a catalyst for the decomposition, but in the presence of oxygen becomes coated with a film of oxide, which is ineffective as a catalyst 12).
