Abstract
Amalgam made with Brewster Alloy (62% Ag, 33% Sn, 5% Cu, and 0.2% Zn) had little or no dimensional change during 24 h at 23 degrees C. Brewster amalgam stored for five yr in air expanded 186, 68, and 14 microns/cm at 60, 37, and 23 degrees C, respectively. Nearly "stable" conditions were approached at about 50 mo.
摘要
由布鲁斯特合金（62%银、33%锡、5%铜和0.2%锌）制成的汞合金在23摄氏度下24小时内尺寸变化很小或没有变化。在空气中储存五年的布鲁斯特汞合金在60、37和23摄氏度下分别膨胀了186、68和14微米/厘米。在大约50个月时接近了几乎“稳定”的状态。
