The indium-sn-bismuth-amalgam contains the following components according to mass content: 38-46% of bismuth, 47-55% of sn, 5.3-9% of indium and 1.3-2.6% of mercury, wherein the mass ratio of the bismuth (Bi) to Sn is less than one. Lamps using the amalgam have high luminous efficiency, good consistency and relatively low cost; and ...

Typically, the LP amalgam lamps use the mercury/indium amalgam, which reaches the optimum mercury vapor pressure at wall temperatures close to 100°C. Thus, a higher fraction of electrical power is used, and their UV output is less dependent on the ambient temperature (Van der Pol & Krijnen, 2005).

The disclosure relates to fluorescent lamps and methods of manufacture wherein the mercury is dosed into the lamp in a solid material containing mercury, bismuth, indium and another metal. In one embodiment, the metal is selected from the group consisting of zinc, tin, lead, silver, gold, copper, gallium, titanium, nickel, and manganese.

Accepted 10 August 1961) Summary The radiochemieal separation of indium by an amalgam-exchange technique has been critically evaluated for the aqueous hydrogen bromide system. The efficiency and contamination of the separation has been studied using tracers of 19 different representative elements. Yields of con- taminating elements are …

Amalgam is a combination of metals that has been the most popular and effective filling material used in dentistry for the last 150 years. Although it sometimes is called "silver amalgam," amalgam actually consists of a combination of metals. These include silver, mercury, tin and copper. Small amounts of zinc, indium or palladium also may be used.

Copper amalgam is known for its high corrosion rate, giving it increased antibacterial effects (Örstavik 1985). In a document from the Nordic Institute of Dental Materials (NIOM), the head of the institute calculates that a child with copper amalgams in all molars (10 g) could be exposed to 2.3 g of mercury and 1.0 g of copper annually in a ...

N. Ahern, in Gold Ore Processing (Second Edition), 2016 3 Mercury in Artisanal and Small-Scale Mining. Mercury is used to extract gold by forming a gold–mercury amalgam in artisanal and small-scale gold mining (ASGM). Almost all of this mercury is lost to the environment when the amalgam is heated to purify the gold, at an estimated 1400 metric …

Dental amalgam was once one of the most common materials used to fill cavities. Also known as "silver fillings," amalgam fillings are silver in appearance but not in composition. Since many dentists now use tooth-colored materials to fill cavities and restore teeth, amalgam fillings are less common than in the past.

The results of kinetic measurements revealed an accelerating effect of acetazolamide (ACT) on the multistep In(III) ions electroreduction in chlorates(VII) on a novel, cyclically renewable liquid silver amalgam film electrode (R–AgLAFE). The kinetic and thermodynamic parameters were determined by applying the DC polarography, …

The purpose of this study was to clinically evaluate two formulations of a dispersed-phase, high-copper dental amalgam alloy (Indisperse), which contained admixed indium. One alloy tested contained 5% indium, and the second alloy contained 10% indium. A similar alloy without indium, Dispersalloy, was also placed for comparison.
