Surface analysis of dental amalgams by X-ray

2003-11-1  The surface composition of indium containing amalgam (Indiloy) showed a typical enrichment of indium up to 80 at% of the metallic element. The oxygen content in fresh surfaces was approximately 30–40 at% regardless of the type of amalgam, while the oxygen contents increased up to around 60 at% after aging.

The surface of the In-containing amalgam was rapidly covered with both indium and tin oxide films. Greater amounts of oxygen were found on the gamma 1 Ag-Hg matrix in the In-containing amalgam

Surface characterization of amalgam made with Hg-In

The surface of the In-containing amalgam was rapidly covered with both indium and tin oxide films. Greater amounts of oxygen were found on the gamma 1 Ag-Hg matrix in the In-containing amalgam than in the amalgam without indium. The rapid formation of the oxide film contributes to a reduction in the mercury release from the In-containing

At a surface charge of −10 μC/cm 2, the capacity varies from 15 μF/cm 2 for mercury to 20 μF/cm 2 for 64% indium amalgam. At a surface charge of +10 μC/cm 2, the capacity of a 64% indium amalgam is approximately twice that of mercury. The potential drop across the diffuse

1985-3-8  The electrocapiliary curves of indium amalgams [4,5] indicate a strong negative adsorption of indium at the surface This perhaps results in the surface of the amalgam behaving more like the mercury surface Any small differences in the surface composition are reflected only when considerable adsorption forces come into operation Thus differences

Surface analysis of dental amalgams by X-ray

Objectives: It is important to characterize the surface of dental amalgam in order to understand the process of mercury release from amalgam restorations in the oral cavity. The mercury evaporation occurs not only from the newly made restoration but also from the set material. Methods: The surfaces of four different types of amalgams, which had been well set, were analyzed with X-ray

Liquid Alloys. A range of alloys that remain liquid at room temperature. Alloys that contain gallium have the intriguing property of remaining in the liquid state at room temperature and below. While pure gallium melts at 30°C, alloying gallium with indium, tin, and/or zinc lowers the melting point even further.

In still another embodiment, the amalgam composition includes about 28.8 wt. % indium, 67.4 wt. % bismuth, 0.85 wt. % zinc and 2.9 wt. % mercury. Because the amalgam according to the embodiments of the disclosure can be substantially solid at room temperature, the amount of amalgam for use in a lamp can be easily quantified and dispensed.

Indium reduces creep and increases strength, while palladium decreases corrosion and tarnish (tarnish is damage of luster from the metal or amalgam surface due to formation of a surface coating). The alloy remains unaffected and its mechanical characteristics remain the same. The sulfide layer formed on the surface causes amalgam to tarnish.
