ある。However, these alloys were kneaded at a weight ratio of 0.85 mercury to Alloy 1, and their physical properties were tested for 24 hours in accordance with Japanese Industrial Standard (JIST6109) Alloys for Dental Silver Amalgam. When measured later, the results were as follows: Pressure deformation: about 2%, curing expansion: 0 to -10μ/CrrL, and crushing resistance: 2300 to 3200k19/Cr7L.

、市販しているのが現状である。Therefore, in recent years, a method has been developed in the United States to reduce the so-called r2 phase by adding a large amount of a silver-copper eutectic alloy called high copper to the conventional dental silver amalgam alloy. Currently, in Japan, various dental material manufacturers manufacture and sell them commercially.
しかし、ｒ２相は減少するが、他の物理的性質はあまり
効果を上げていないのが現状である。However, although the r2 phase is reduced, the current situation is that other physical properties do not have much effect.
