[A new direction in the development of Russian silver amalgams. I. The physical research].
A new in principle, ecologically safe and low-waste technology for preparation of an alloy and a formula of several silver alloys containing different levels of silver (OCTA-43, 70 and 80) have been developed. The absence of a alpha-2 phase in amalgams prepared from these alloys is their principally new feature. Physical properties of the new alloys were studied and compared with the known Russian and foreign analogs. Amalgam prepared from CCTA-43 alloy is characterized by optimal characteristics. By their physical characteristics the new compositions are superior to traditional and silver alloys manufactured in Russia at present, and amalgam prepared from OCTA-43 alloy is not inferior to the best foreign analogs.
