[A finely dispersed copper alloy for amalgams. 1. The physical studies].

The authors present the results of physical studies of a new generation of copper amalgam: capsulated, obtained from a newly developed alloy, permitting preparation of fillings in an amalgam-mixer capsule by mixing the powder with mercury at room temperature. Copper finely dispersed amalgam (CFDA) alloy powder is characterized by a regular shape of structural components. This feature permits accurate dosage and helps prepare fillings characterized by good reproducibility. Copper amalgam prepared from CFDA alloy is characterized by high color stability and corrosion resistance, is rapidly hardening and strong as against amalgams currently used both in Russia and abroad.
