Silver cadmium, primary

Primary batteries. Silver compounds such as AgO are used as cathode materials for making high-capacity silver-zinc and silver-cadmium primary batteries. Silver paints are used for making printed circuits.

Metal compounds, particularly compounds of the heavy metals, have a history of importance as antimicrobial agents. Because of regulations regarding economic poisons in the environment they are no longer widely used in this appHcation. Mercury, lead, cadmium, uranium, and other metals have been imphcated in cases of poisoning that resulted in government response. The metals whose compounds have been of primary interest as antimicrobials are mercury, silver, and copper. 

Codeposition of silver vapor with perfluoroalkyl iodides at -196 °C provides an alternative route to nonsolvated primary perfluoroalkylsilvers [272] Phosphine complexes of trifluaromethylsilver are formed from the reaction of trimethyl-phosphme, silver acetate, and bis(trifluoromethyl)cadmium glyme [755] The per-fluoroalkylsilver compounds react with halogens [270], carbon dioxide [274], allyl halides [270, 274], mineral acids and water [275], and nitrosyl chloride [276] to give the expected products Oxidation with dioxygen gives ketones [270] or acyl halides [270] Sulfur reacts via insertion of sulfur into the carbon-silver bond [270] (equation 188)... 

There are two major types of household batteries (a) Primary batteries are those that cannot be reused. They include alkaline/manganese, carbon-zinc, mercuric oxide, zinc-air, silver oxide, and other types of button batteries, (b) Secondary batteries are those that can be reused secondary batteries (rechargeable) include lead-acid, nickel-cadmium, and potentially nickel-hydrogen. 

Analyses of bullion lead from primary and secondary sources are given in Table 15.2. The data show that the main impurities found in secondary lead are the major constituents of the lead alloys used in the construction of the battery, namely, antimony, tin, arsenic, and copper, whilst minor contaminants include nickel, cadmium, sulfur, bismuth, and silver. 

Effect of Increasing Valency of Solute. It has been found that when size-factors are favourable extended solid solutions are most lilcely to be formed when the metals concerned have atoms with the same number of outer-layer electrons, i.e. when they have the sa ne valency. When size-factors arc favourable and valencies unequal tin4 extent of solid solubility will decrease as the difference between the respective valencies increases. To examine the effect of the valency-factor we may consider the extent of the solid solubility in copper ((1u).of the favourable size-factor but increasing valency metals, zinc (Zn), gallium (Ga), germanium (Ge) and arsenic (As), and in silver (Ag) of the corresponding favourable size-factor metals, cadmium (Cd), indium (In), tin (Sn) and antimony (8b). The necessary atomic diameters and valency data (vide p. bl), and the results of experimental work on these1 alloys, as far as the primary solid solutions are concerned, an1 summarised in Fables IX (a) and (h). 

The aerosols of the low-volatility substances which enter the primary system of the reactor consist mainly of refractory oxides of the less volatile fission products, as well as of those of the core structural and component materials metals such as silver and cadmium from the PWR control rod materials are also present. In addi-... 

In principle, tellurium deposition on stainless steel in the primary system would largely prevent this element from being released to the containment. However, tellurium vapor could react chemically with a variety of metallic aerosols to form tellurides in particular it has a high affinity for silver and cadmium, as well as for tin volatilized from the Zircaloy claddings. Thus, tellurium transport through the primary system would be primarily controlled by aerosol transport characteristics. Spence and Wright (1987) have calculated that inclusion of these processes of depo-... 

The intracellular localization of stress proteins is problematic for the evaluation of the response in humans. Because the cells for the assay of stress proteins are not readily available through noninvasive procedures, the application of this response to human monitoring is limited. Recently, however, enhanced synthesis of stress proteins was demonstrated in primary cultures of human lymphocytes exposed to several metals (Yamada and Koizumi 1993). The specificity of the response was dependent on the metal to which the cultures were exposed. For example, cadmium and zinc induced both hsp70 and MT, while cobalt and triphenyltin induced only hsp70. Conversely, copper, mercury, nickel, and silver all induced synthesis of MT, but not of hsp70. Enhanced synthesis of stress proteins has also been demonstrated in vivo in lymphocytes and spleen cells excised from mice exposed to hyperthermia (Rodenhiser et al. 1985).
