OP thinks a bunch of Americans deserve to punished (potentially die), not because of any of their actions, but because the government and private groups (who will be the least effected) victimize said Americans. The beatings will continue until the economy improves, fucking genius.
I used to work for a foreign company in the US that made this stuff. All the crucibles were made out of graphite, never saw a quartz crucible, maybe they are used in the making of them via ingredient or mold, or maybe they produce a different quality of silicon. We “grew” the silicon into these big (ranging from 2-4ish ft long) cylinder like crystals where they would be shipped off to another area to be sliced into thin wafers for chips. The crucibles were good for maybe I think under 100 runs before they needed to be replaced if they didn’t fail before that.
