Porosity in silver-tin amalgams

Porosity has been determined metallographically for a series of spherical silvertin amalgams. The alloy consisted of separate size fractions of five compositions. Porosity was found to increase with increasing silver content and particle size, and was reduced by blending of large and small particle...

Description
Summary:Porosity has been determined metallographically for a series of spherical silvertin amalgams. The alloy consisted of separate size fractions of five compositions. Porosity was found to increase with increasing silver content and particle size, and was reduced by blending of large and small particle sizes. In blended alloys the porosity showed close correlation to the observed setting expansion.
