Silver plating, applications

Silver chloride is used in silver plating and to obtain pure silver. The salt also finds applications in photography and optics in photochromic glass and in electrodes and batteries. It is used to make antiseptic silver solution. It occurs as the mineral cerargyrite. 

Most electroless silver applications are for silvering glass or metallizing record masters. Mirror production is the principal usage for electroless silver. The glass support is cleaned, catalyzed using a two-step catalyst, and coated on one side with an opaque silver film (46). Silver-plated nylon cloth is used as a bacteriostatic wound dressing. A tiny current applied to the doth causes slow silver dissolution. The silver acts as a bactericide (47).

OTHER COMMENTS silver metal and soluble silver compounds have applications in the following list of common operations used in the manufacture of silver nitrate for use in photography, mirrors, inks, dyes, and porcelain used in the manufacture of silver salts as catalysts in oxidation-reduction and polymerization reactions also utilized in chemical synthesis, in glass manufacture, in silver-plating, in photography, as laboratory reagents, and in medicine. 

The work of Ambrosino and colleagues has already been mentioned. The early volumes of the journal Archaeometry (first published in 1958) also contain some exploratory research on the application of NAA to the problem of coin analysis. Kraay and Emeleus at Oxford realized that NAA was a very practical solution to one of the requirements of ancient coin analysis, and that was, for the rare and most valuable specimens at least, that it be totally non-destructive. They also quickly discovered another benefit because neutrons activated the whole coin, they provided a bulk analysis as opposed to x-ray fluorescence, which gave only the surface composition. They found that a Corinthian coin, thought to be silver, was in fact silver-plated over a copper core. For precise NAA studies, the self absorption of neutrons in solid gold coins requires a substantial correction to the flux. Self absorption in silver, less serious has also been investigated (see below). 

Depends on Internet research. Some electroplating companies do emphasize cosmetic silver plating, so the paper could support the assertion. It is more likely that the site found will have more industrial applications for silver plating, and a paper would reflect that fact. 

In the continuous process of purification, the bath is continuously passed through a bed of activated carbon, which is changed from time to time. In this process the bath is almost free of undesirable impurities. However, it is not applicable to baths containing easily absorbable desirable components of the bath. This is especially true for silver plating solutions containing carbon disulfide. ... 

Our efforts in this area were initiated in 1995 with investigations of the electrodeposition of silver (26, 27) and, soon thereafter, platinum (28) nanoparticles on HOPG surfaces. The primary characterization tool employed in these experiments was ex situ non-contact atomic force microscopy (NC-AFM). In the silver work, HOPG electrode surfaces were examined by NC-AFM after the application of large amplitude potentiostatic pulses with amphmdes of —100 to —500 mV (vs. Ag/Ag+) and durations of 10-50 msec in dilute silver-plating solutions. These images looked dramatically different from the... 

In applications where really high temperatures of up to 200 C may be encountered, Cornell Dubilier offers mica and Teflon (PTFE) electrolyte metal clad versions in silver-plated metal cases. These designs, which feature ultra-low inductance terminations and heat spreading when operating at high power, assure low ESR (Equivalent Series Resistance) to greater than 1 GHz, and high ripple current capabilities with stability in subminiature sizes.

One of the most effective techniques used to improve the electrical conductivity of polymers is the incorporation of conductive fillers in the polymer matrix. The most popular electrically conductive filler is silver due to its moderate cost and superior conductivity. Silver-coated inorganic particles and fibers are superior compared to carbon particles and fibers as components in epoxy-based adhesives regarding the electrical conductivity of the composite because the electrical conductivity of silver is much higher than that of carbon. In addition to the high electrical conductivity of silver, the addition/application of silver-plated... 

Alternative metals are also suitable such as copper, silver and silver plated copper, depending on the degree of conductivity required. Bentone SD-2 induces some thixotropy into the coating to aid stability and application. 

Electronic Applications. The PGMs have a number of important and diverse appHcations in the electronics industry (30). The most widely used are palladium and mthenium. Palladium or palladium—silver thick-film pastes are used in multilayer ceramic capacitors and conductor inks for hybrid integrated circuits (qv). In multilayer ceramic capacitors, the termination electrodes are silver or a silver-rich Pd—Ag alloy. The internal electrodes use a palladium-rich Pd—Ag alloy. Palladium salts are increasingly used to plate edge connectors and lead frames of semiconductors (qv), as a cost-effective alternative to gold. In 1994, 45% of total mthenium demand was for use in mthenium oxide resistor pastes (see Electrical connectors).
