Material and Composition
A commercial Ag–Pd–Cu–Au alloy (Kinpara S 12,
Ishifuku Co. Ltd, Tokyo, Japan) was used in the
study. Specimens were cut from the ingot and from
recast specimens, dissolved in acid, and the
solutions were analyzed using an inductively
coupled plasma emission spectrometer (ICPV-1012
Shimadzu Co. Ltd, Kyoto Japan). The results are
shown in Table 1.
