DENTAL ALLOY CONTAINING SILVER

摘要

A process for manufacturing an atomized amalgamable alloy having mold adaptation characteristics superior to other atomized alloys and comparable or better than those for ad-mixed type alloys (alloys which are mixtures of spherical and irregularly shaped particles), and physical properties comparable to ad-mixed alloys. The process includes the steps of: producing a melt of an amalgamable alloy; atomizing the alloy so as to form particles which are primarily irregular in shape; collecting the particles; drying the particles; mechanically working the particles so as to fracture and change their shape; classifying the particles to finer than 53 microns; heat treating the particles; and reducing oxides from the surface of the particles.
