  2. Amalgam (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Amalgam_(chemistry)

    An amalgam is an alloy of mercury with another metal. It may be a liquid, a soft paste or a solid, depending upon the proportion of mercury.

  3. Amalgam (dentistry) - Wikipedia

    en.wikipedia.org/wiki/Amalgam_(dentistry)

    Amalgam is a mixture of two or more metals (alloy) with mercury which has been purified first by distillation to remove impurities. Major components of the alloy are silver, tin, and copper. The composition of the alloy powder is controlled by ISO standard for dental amalgam alloy (ISO 1559) to control the properties of amalgam. [11]

  4. Dental material - Wikipedia

    en.wikipedia.org/wiki/Dental_material

    Amalgam is a metallic filling material composed from a mixture of mercury (from 43% to 54%) and a powdered alloy made mostly of silver, tin, zinc and copper, commonly called the amalgam alloy. [16] Amalgam does not adhere to tooth structure without the aid of cements or use of techniques which lock in the filling, using the same principles as a ...

    en.wikipedia.org/wiki/Dental_restoration

    Improvements in the understanding of the structure of amalgam post-1986 gave rise to copper-enriched amalgam alloys, which contain between 12 wt% and 30 wt% copper and at least 40 wt% silver. [12] The higher level of copper improved the setting reaction of amalgam, giving greater corrosion resistance and early strength after setting.

  6. Aluminium amalgam - Wikipedia

    en.wikipedia.org/wiki/Aluminium_amalgam

    Aluminium amalgam may be prepared by either grinding aluminium pellets or wire in mercury, or by allowing aluminium wire to react with a solution of mercury(II) chloride in water. [ 1 ] [ 2 ] This amalgam is used as a chemical reagent to reduce compounds, such as the reduction of imines to amines .

  7. Talk:Amalgam (dentistry) - Wikipedia

    en.wikipedia.org/wiki/Talk:Amalgam_(dentistry)

    An amalgam is an alloy composed of mercury and other metals.[1] Dental amalgam is produced by mixing liquid mercury with an alloy made of silver, tin, and copper solid particles.[1] Small quantities of zinc, mercury and other metals may be present in some alloys.[1] This combination of solid particles is known as amalgam alloy.[1]

  8. Dental amalgam controversy - Wikipedia

    en.wikipedia.org/wiki/Dental_amalgam_controversy

    This discussion of the dental amalgam controversy outlines the debate over whether dental amalgam (the mercury alloy in dental fillings) should be used. Supporters claim that it is safe, effective and long-lasting, while critics argue that amalgam is unsafe because it may cause mercury poisoning and other toxicity .

  9. Alloy wheel - Wikipedia

    en.wikipedia.org/wiki/Alloy_wheel

    Alloy wheels have long been included as standard equipment on higher-priced luxury or sports cars, with larger-sized or "exclusive" alloy wheels being options. The high cost of alloy wheels makes them attractive to thieves; to counter this, automakers and dealers often use locking lug nuts or bolts which require a special key to remove.
