Abstract

Investigation of dissolution of base metal dental casting alloy constituents in aqueous solutions revealed an unexpectedly high level of beryllium as compared with the other constituents. Analysis of atomic emission spectroscopy is presented here showing the outer surface (0-100 A) is decidedly enriched in beryllium as compared with the bulk composition of the alloy. This localization is consistent in all samples and forms of the alloy tested.

摘要

对贱金属牙科铸造合金成分在水溶液中的溶解情况进行的调查显示，与其他成分相比，铍的含量出奇地高。本文展示了原子发射光谱分析结果，表明与合金的整体成分相比，合金外表面（0 - 100埃）的铍明显富集。在所有测试的合金样品和形态中，这种局部化现象都是一致的。
