terbium

> To quantify this influence, the team applied their model to Terbium Gallium Garnet (TGG), a crystal widely used to measure the Faraday effect.

Lynas Rare Earths noted in it's last quarterly report that it has started it's HRE separation circuit and will begin producing Dysprosium this month (May 2025), followed by Terbium in June at it's Malaysian site.

Or its cousins, ytterbium, terbium, and erbium, all of which were first refined out of an obscure mineral, ytterbite, and all named with a stunning deficit of creativity.

It appears to have about the same proportion of neodymium and praseodymium (valuable light rare earth elements used in magnets) as the Mountain Pass, California mine, plus more terbium (more expensive heavy rare earth element also useful in magnets) than Mountain Pass.

In this world, gold would still cost around 800 dollars an ounce to mine; but the only difference would be the market cap for gold would be very small and would serve its niche applications (comparable to the market for terbium or platinum).

Other glasses that glow under UV: * Cerium (blue white) * Dysprosium (yellow-white) * Europium (orange) * Manganese (orange) * Samarium (orange) * Terbium (green) I've only been able to find small samples of these, so I don't know how much glassware there is compared to uranium, though.

Electric motor materials include aluminum, cobalt, copper, iron, silicon-steel, manganese, graphite, lithium, and a variety of rare-earth minerals (dysprosium, neodymium, niobium, terbium and praseodymium).

Paper: > 17.5% of the measured value for Terbium-Gallium-Garnet (TGG) at 800 nm, and up to 75% at 1.3 µm.

It requires blasting to extract from the bastnasite and is low in heavy rare earths such as Dysprosium and Terbium.
