Liquid alloys are used in many evolving applications currently being developed in research and development labs around the world. Liquid alloys enable these applications, not only because of their ultra-low …

Amalgam is a metal alloy of which one of the elements is mercury (Hg). Alloys are metals that are a combination of several elements. Dental amalgam is made by mixing approximately equal parts (by weight) of a powdered metal alloy with liquid mercury. The powdered metal is called an amalgam alloy and is predominantly silver (Ag) and tin …

High-copper amalgam alloys containing 5% and 10% admixed indium, shown in previous studies to have improved properties and acceptable biological behavior, were evaluated in a clinical study designed to examine factors relating to clinical success. One hundred and seventy-five Class I and Class II amalgam restorations were placed in 25 patients.

Dental amalgam has been around for hundreds of years and is still used extensively even today, despite potential concerns to both patient and clinical staff associated with mercury processing. Amalgamation constitutes the reaction with liquid mercury with any reactive metal. Mercury reacts with a range of metal powders that have been ground (using …

An amalgam is an alloy consisting of one or more metals that is combined with mercury. The primary benefit of an amalgam is that the mercury vapor pressure of an amalgam is lower than mercury alone (at the same temperature). ... First Light Technologies, Inc. has developed a complete line of amalgam lamps. Indium is the ideal metal for this ...

Copper, silver, and tin are the major components in dental amalgam but it may also contain zinc, indium, mercury, gold, platinum, and palladium. 2, 12, 13 …

Abstract. The purpose of this study was to evaluate the effect of admixed indium on the amount of mercury vapor released from dental amalgam. We made amalgam …

Indium is an amphoteric element; it dissolves in acids to give indium salts, and it also dissolves in concentrated alkalies to give indates. However, it is unaffected by potassium hydroxide or boiling water. When heated in the presence of the halogens or sulfur, direct combination takes place.Though a few authentic indium compounds (e.g., …

High-copper amalgam includes 40-60% silver, 27-30% tin and 13-30% copper and 1% zinc set with mercury. Indium and palladium are also included. Silver enables setting expansion and causes an increase in strength and resistance to corrosion.

Indium is used in amalgam alloys used for dental purposes. It is used as control rod in nuclear reactors. Radioactive isotope of indium (indium-111) is used in nuclear medicine studies for the movement of blood cells in …

Amalgam (Johnson & Johnson, East Windsor, N J), gutta-percha (Sybron/Kerr, Romulus, MI), and indium foil (Indium Corporation of America, New York, NY) in sheets 0.6-mm thick (99.99% indium) were used in the immediate repair of the mechanical perforations. The three materials were randomly assigned to one tooth

Classified under the In symbol in the periodic table, with an atomic number 49, atomic mass of 114.82 g.mol-1, and electron configuration [Kr] 4d105s25p1, the chemical element indium is a soft, ductile, corrosion-resistant, and malleable metal with a plasticky feel to it. With its lustrous silvery-white color, it resembles tin in appearance.

Results showed that a low-copper amalgam containing 10% indium had 40% less of the tin-mercury phase compared to a similar amalgam without indium. Youdelis and Youdelis (1981) later added 1.5% germanium to the silver-copper eutectic spheres in the admixed alloy to reduce oxidation of the spheres during processing. This change was …

It can be concluded that the admixture of 5-10% indium as well as the increased ratio of eutectic spheres to lathe-cut particles found in the indium alloys enhance the clinical performance of amalgam restorations. The purpose of this study was to clinically evaluate two formulations of a dispersed-phase, high-copper dental amalgam alloy (Indisperse), …
