What is Amalgam?
An '''amalgam''' is a solution,liquid or solid, of a [[metal]] in [[mercury (element)|mercury]]. It is a type of [[alloy]]. Many metals can dissolve in mercury. Amalgams are used in tooth fillings. Platinum and iron cannot form amalgams. [[Gold]] can dissolve in mercury, which is used to separate gold from its [[ore]]. [[Aluminum]] forms an amalgam which can react with water because the thin [[Alumina|oxide]] coating on the aluminum is dissolved. ==Related pages== *[[Chemical compound]] *[[Mixture]] *[[Alloy]] {{chem-stub}} {{authority control}} [[Category:Chemicals]] [[Category:Alloys]]
