Abstract

Two copper-free amalgams expanded excessively after storage in air at 60 degrees C for about five yr. One expanded significantly at 37 degrees C and slightly at 23 degrees C. High silver content, absence of copper, and presence of small amounts of zinc, or all three, seemed to promote very high expansions at 60 degrees C.

摘要

两种无铜汞合金在60摄氏度空气中储存约五年后过度膨胀。一种在37摄氏度时显著膨胀，在23摄氏度时略有膨胀。高银含量、无铜以及存在少量锌，或这三者同时存在，似乎会促使合金在60摄氏度时产生非常高的膨胀。
