Yes. Some semiconductors are made from gallium arsenide and gallium arsenide
phosphide.

I have been watching this child troll for a while now. He shows up about
once a month under a different name and posts some inane low level dreck that
a moron would be ashamed of. He has no imagination whatsoever.
On the other hand Google search turns op 588 posts between Dec. 11 and Dec.
14 That is quite some output. I am starting to suspect a artificial
stupidity.

Well, some kind of stupidity, it seems. He posted something on a tea
group saying some teas have "letal" doses of Americium Fluoride. I
can't even imagine where you'd FIND Americum Fluoride, except possibly
at a nuclear reactor.

Give the troll credit for a couple neurons. Most trolls wouldn't even
spell gallium or americium right. (by the way, he's also creating
musical instruments on rec.music.makers.builders - clearly a versatile
troll).

Gallium melts at 29.78 deg. C so casting is the way to go. [Actually,
molten gallium is pretty cool stuff. Acts a lot like Mercury if you have
it in warm water, but it doesn't absorb through your skin, and then
freezes instantly when you pour it on a surface. They used to use it for
optically flat telescope secondary mirrors because you could melt in a
form and get a surface that was within a couple atoms of totally flat.]

One isotope of Americium has a half life of ~7000 years so you could
produce a fluoride (probably AmF6). Since it's an actinide and they act
like lanthides, which is to say, like clays, the fluoride ions would
probably be more toxic than the Americium. But Americium is an alpha
emitter and those beasts are hard on cell walls. So a "letal" dose has
several possible meanings (not the least of which being shot by the
guards when you tried to get it out of a military reactor facility). But
you could probably find your tea in the dark :-)
