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 400 mesh sieve. Only phases expected at room temperature have been produced thus far.

## 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
## Abstract Background: This study aimed to compare the cytotoxicity of baseβmetal dental alloys and to evaluate if the casting method could influence their cytotoxicity. Methods: Disks of baseβmetal dental alloys were cast by two methods: plasma, under argon atmosphere, injected by vacuumβpressure
## Abstract Dental amalgams are based on a broad spectrum of materials differing in their chemical composition, metallurgical treatment, and in the way the initial alloys powders are prepared. In addition to their chemical composition, amalgams based on various powders differ in both their microstr
