Welcome aboard, Engineer!
I'll bet that helium works in glass like it does in water: if you put enough through there, it displaces the other gases from solution. But helium is so poorly soluble (at least in water or crude oil) that very little stays behind to form bubbles. (We use helium to "degas" solutions before pumping them through core samples in the petroleum biz.)
I'd imagine that the reason helium is poorly soluble is that it's a very small nonpolar atom. Argon is nonpolar, too, but far more polarizable, so I'm betting it's more soluble.

Lead zirconate titanate is a good piezo material:
That's nice. Lead zirconate titanate is also as chemically distinct from zircon, which is zirconium silicate, as sodium chloride is from sodium cyanide. Lead won't fit in a zirconium silicate crystal lattice, and sodium cyanide doesn't belong on your pretzels.
I think the lead is right in there with the zirconium as a chemical compound.
Of course it is, in that chemical compound. PZT has a perovskite crystal lattice, zircon is tetragonal. PZT is man-made, zircon magma-made. They aren't the same.
