or spherical particles. High-copper alloys contain either spherical particles of the same composition (unicompositional) or a mixture of irregular and spherical particles of different or the same composition (admixed). The properties of set amalgam depends upon the alloy composition--particle size, shape and distribution--and heat treatment controls the characteristic properties of the amalgam.

Low copper alloy

During trituration, mercury diffuses into the silver-tin particles. Then, silver
