· 1) When a model electrolyte (/lSnCl 2, /lIn 2 (SO 4) 3, 2 SO 4, /lH 2 SiF 6) was electrolyzed usinga tin anode and a mercury hode, the current efficiency of theanodic dissolution of tin was 100% at the current density below10A/dm 2, and at the hode the mixture amalgam of tin and indium was obtained efficiently without hydrogen evolutionat the current .

Preliminary work1 also indied that indium could be readily adapted to this type of separation. Sunderman and others6p8 have given extensive yield and concentration data on a number of radiochemical separations of indium which can form a solid basis for a general evaluation of this amalgamexchange method versus standard separation techniques.

, Indium containing admixed highcopper amalgam exhibited a reduction in creep and increase in strength. Youdelis also found that less mercury is required for mixing amalgam when it contains indium in concentration up to 10%.
Dental amalgam has served as an excellent and versatile restorative material for many years, despite periods of controversy. The authors review its history, summarize the evidence with regard to ...
Indium is present in Earth's crust in around ppm. It is not present in elemental or free form. Indium does not have any ore that contain high concentration of this metal. Naturally, it is present in little amounts with ores of copper, lead, iron and zinc. Commercially, indium is obtained as a byproduct during the refining of zinc sulfide ...
An electrodeless fluorescent reflector lamp has a discharge vessel containing a fill, a solenoid in a reentrant and indium on the inner wall of the vessel acting as a primary amalgam. A secondary amalgam of indium may be provided on the reentrant. The primary amalgam is preferably under an insulative skirt. The vessel has a light reflective coating on the inner wall under the skirt.

Indium (or, formerly, mercury) is added to batteries to suppress corrosion that can cause batteries to burst. Indium is also a frequent addition to dental amalgam fillings (the shiny, metallic ones). Dental amalgams contain mercury, which can be toxic if it is swallowed or inhaled. Indium helps to keep mercury in the filling,
Title: PbFree Solder Paste 98485 R21 Author: Indium Corporation Subject: is an air reflow, noclean solder paste specifically formulated to accommodate the higher processing temperatures required by the SnAgCu, SnAg, and other alloy systems favored by the electronics industry to replace conventional Pbbearing sold ers.
In Copper 1895, G. V. Black published a dental Mercury amalgam formula that • Other elements. provided for the Zinc most clinically Indium acceptable Palladium performance, and his recipe remained unchanged for Silver (Ag) virtually seventy years. Increases strength and hardness. In 1959, Dr. Wilmer Eames suggested a Increases modifiion to ...
Indium is added to some dental amalgam alloys to decrease the surface tension of the mercury and allow for less mercury and easier amalgamation. Indium's high neutroncapture crosssection for thermal neutrons makes it suitable for use in control rods for nuclear reactors, typically in an alloy of 80% silver, 15% indium, and 5% cadmium.
· Researchers at ETH have managed to produce nanocrystals made of two different metals using an amalgamation process whereby a liquid metal penetrates a solid one. This new and surprisingly ...
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.
