DENTAL ALLOY WITH A HIGH GOLD CONTENT THAT IS DEVOID OF PALLADIUM AND COPPER

摘要

The invention relates to a dental alloy with a high gold content that is
devoid of palladium and copper. To achieve a high mechanical stability, the
dental alloy consists of between 75 and 95 wt. % Au, between 5 and 20 wt. %
Pt, between 0.5 and 3.5 wt. % Zn and/or Sn and/or In, between 0.1 and 0.8 wt.
% of an element of a group I, in addition to a single particle refiner of a
group II. The weight fraction of the element of group I is between 2 and 6
times that of the single particle refiner of group II, and one element of the
group I is represented by Nb or Ta or Ti or V and the particle refiner of
group II is represented by Ir or Rh.
