## Abstract Splat cooling has been used for the preparation of dental alloy in the form of ribbons of 5β25 ΞΌm in thickness. The powdered alloy was produced by shaking the ribbons with a dental pestle in a mechanical amalgamator. One minute shaking produced a powder all of which passed a standard 40
## Abstract Improved techniques in preparing and sizing dental alloy powders containing Ag, Sn, and Cu have led to amalgams with higher strengths and less spread in dimensional change but very poor shelf life. Since maximum strengths occurred for amalgams containing about 15% more Sn than previousl
Strength, dimensional change during setting, and corrosion resistance have been measured for amalgams prepared from splat-cooled alloys of different compositions in the Ag-Sn-Cu system. The amalgam with optimum values of these properties was made from the alloy containing 60 at. Ag, 25 at. % Sn, an
