COMPOSIZIONE DENTARIA E RELATIVA AMALGAMA

摘要

A composition suitable for amalgamation with mercury to form a dental amalgam comprising a substantially uniform blend of a major proportion by weight of the first alloy in the form of spheroidal particles consisting essentially of about 24 to 45 weight percent silver, 28 to 42 weight percent copper and 29 to 34 weight percent tin, and where the atomic percentage of the total amount of silver plus copper is about 3 times greater than the atomic percentage of tin; and a minor proportion by weight of a second alloy in the form of irregularly-shaped particles having the same composition as the first alloy.
