By "compound", I generally mean something like magnesium oxide, where you'd have to do chemical foo to extract the pure element. Whereas ordinary tin/lead solder is just an alloy/mixture, where neither the tin nor lead is chemically combined with anything. The fine silver is pure enough, as far as I'm concerned, unlike one web site which states something like "the highest purity obtainable is just barely good enough".
