An alloy of mercury with another metal (usually silver) used by dentists to fill cavities in teeth; except for iron and platinum all metals dissolve in mercury and chemists refer to the resulting mercury mixtures as amalgams.

Mercury is the only metal which forms amalgams with other metals. Ex: zinc amalgam.
