amalgam

Examples of amalgam in the following topics:

• Mercury

  • Mercury dissolves to form amalgams with gold, zinc, and many other metals.
  • Sodium amalgam is a common reducing agent in organic synthesis, and it is also used in high-pressure sodium lamps.
  • Mercury readily combines with aluminium to form a mercury-aluminium amalgam when the two pure metals come into contact.
  • For this reason, mercury is not allowed aboard an aircraft under most circumstances because of the risk in forming an amalgam with exposed aluminium parts.
  • Mercury is still used in scientific research and as amalgam material for dental restoration.

• Alloys

  • Examples of alloys include materials such as brass, pewter, phosphor bronze, amalgam, and steel.
  • Examples of alloys include materials such as brass, pewter, phosphor bronze, amalgam, and steel.

• Reactions of Substituent Groups

  • The zinc used in ketone reductions, such as 5, is usually activated by alloying with mercury (a process known as amalgamation).

• Reduction

  • This alternative reduction involves heating a carbonyl compound with finely divided, amalgamated zinc. in a hydroxylic solvent (often an aqueous mixture) containing a mineral acid such as HCl.

• The Structure and Properties of Water

  • The solid phase of water is known as ice and commonly takes the structure of hard, amalgamated crystals, such as ice cubes, or of loosely accumulated granular crystals, such as snow.
