More on gallium and its uses:
https://techiescientist.com/uses-of-gallium/
AP did not attempt to explain why all of these rare and exotic minerals and metals and compounds are used in manufacturing...
...because there a bunch of them, explaining all the reasons for using just one of them would basically be the equivalent of a crash course in applied chemistry / manufacturing / physics / engineering, and if you want to get into why these materials are used in lieu of others, well throw logistics and economics into that pile of course work as well.
AP is reporting the news, not being an industry specific journal, or a comprehensive policy impact study.
I agree with you that it was a frustrating read... but having worked as a copy editor, and having provided many different executive reports to various businesses and non profits, I also sympathize with the writer.
This is the kind of topic where you can either do a broad level overview, or you can write a tome for those who really want to dive into all the details to fully understand it... there's no effective way to do a middling approach on such a vast and complex topic.
Fair enough, that makes sense.
https://www.statista.com/statistics/1445285/gallium-share-of-production-worldwide-by-country/
As of 2022, China basically produces all (98.4%) of the world's gallium.
... Statista has much more great info, but unless you want to pay for a subscription or spend a day hopping through proxy IPs... yeah, good luck.
They produce 98% percent of low-purity Gallium. We produce plenty of high purity Gallium, and Gallium, like Germanium, comes from Zinc mining. Which we still do plenty of in the US. So if we need more high quality Gallium, it's not going to be hard to get.
Ah, so it's not a matter of "that's where the gallium is", it's "might as well buy it from China if they're sellin' it", same as the dollar store
Edit: I wouldn't be surprised if the places in the US producing high-quality gallium are using poor-quality Chinese gallium as feedstock though.
They are, but we have plenty of Zinc mining we can get it from ourselves. It's just an economics matter, so we'd subsidize that. We only use enough to fill one truck load per year. So it's likely we'd just get a defense contractor to do it and subsidize it
