Unusually large quantities of antimony — a metal used in batteries, chips and flame retardants — have poured into the United States from Thailand and Mexico since China barred U.S. shipments last year. https://www.japantimes.co.jp/business/2025/07/09/us-minerals-china-export-ban/?utm_medium=Social&utm_source=mastodon #business #rareearths #china #us #trade #mining #gallium #germanium

1️⃣ | #Germanium: #Wundermittel oder gefährliches #Märchen?
Bei ihren Streifzügen auf Esoterikmessen begegnet Luna allerlei Unfug. Eines der Produkte, die unter #Esoteriker:innen und angeblichen #Heiler:innen beliebt sind, ist Germanium. Was es damit auf sich hat, und warum ihr einen großen Bogen darum machen solltet, lest ihr im #SkeptixBlog!

Random #AliExpress finding...
So today I discovered why I was getting weird results in a circuit I was testing the other day. It turns out that some of the 1N60P germanium diodes I have are fakes. They appear to be just a plain silicon diode with a forward voltage of ~0.6V, rather than the actual article's ~0.25V.
They're in the right DO-35 glass package and they've been marked as 1N60P, so someone's gone to the trouble of faking it well - but I can't see why. It can't possibly be that profitable to buy genuine silicon diodes, remark them, and then sell them for just a few pennies extra, can it?
It's not like the sellers that remark a ten-cent opamp as a $10 part - I can see how that's profitable.
Weird.

#China banned exports of a few rare #minerals to the #US. Things could get messier.
#Gallium and #germanium are used to make #semiconductors. Could battery materials be the next target?
This might be only the beginning. China is a powerhouse, and not just in those niche materials—it’s also a juggernaut in #cleanenergy, and particularly in battery supply chains. So what comes next could have significant consequences for #EV and #climate action more broadly.

Chinas jüngste Beschränkungen für den Export kritischer #Mineralien in die #USA, die auf #Gallium, #Germanium, #Antimon und #Graphit abzielen, markieren eine deutliche Eskalation im Tech-#Handelskrieg.
Dieser Schritt ist ein direkter #Gegenschlag der US-Sanktionen gegen chinesische #Halbleiter und unterstreicht die wachsende Spannung zwischen nationaler Sicherheit und wirtschaftlicher Abhängigkeit.
Die #USA müssen nun nach alternativen Quellen suchen.

Chinese curbs on exports of three niche metals to the U.S. have already rattled the market. Now, a bigger clampdown looks set to have far-reaching ramifications for American defense and chipmaking industries. https://www.japantimes.co.jp/business/2024/12/23/markets/metal-markets-chinese-clampdown/?utm_medium=Social&utm_source=mastodon #business #markets #metals #batteries #electricvehicles #semiconductors #china #mining #us #trade #tech #gallium #germanium #antimony #solar #renewables

Pricing for key chipmaking material hits 13-year high following Chinese export restrictions — #China's restrictions on #Gallium exports hit hard
China is the primary global supplier, accounting for 94% of gallium production. Prices rose to $595 per kilogram, a 17% increase over the previous level on December 11, the highest price since 2011. This sharp increase follows China's latest export ban of critical minerals to the US, including gallium, #germanium, and #antimony.

What #China’s critical #mineral ban means for the #US
In explicitly cutting off, rather than merely restricting, materials of strategic importance to the #semiconductor, #defense, and #electricvehicle sectors (#gallium, #germanium, #antimony), China has clearly crossed a new line in the long-simmering #tradewar. The nation has signaled it’s prepared to hit back harder still, in ways that could inflict serious #economic pain on its biggest economic rival.

#China bans export of key #minerals to #US as trade frictions escalate
China has banned exports to the #UnitedStates of items related to the minerals #gallium, #germanium and #antimony that have potential military applications, it said on Tuesday, a day after Washington's latest crackdown on China's chip sector.
Gallium and germanium are used in #semiconductors, while germanium is also used in infrared technology, #fibreoptic cables and #solar cells.

Hier ein älteres Foto von zwei gekreuzten 1D-Wellenleitern.
Auf ein Substrat (hier: #Germanium) wird erst eine blockierende Schicht (Molybdän), dann die leitende Schicht (#Kohlenstoff) aufgedampft; in diesem Fall ca. 9 #Nanometer (also vielleicht zwei bis drei Dutzend Atomschichten), darauf wieder #Molybdän.
Der Wafer wird auf eine „Länge” von etwa einem viertel Millimeter gesägt (ja, da gibt es extra Sägen für, die das können); eine zweite solche Lamelle wird unter 90° gedreht aufgeklebt. -
A team including researchers at Argonne and the National High Magnetic Field Laboratory (MagLab) discovered surprising properties in a #magnetic material of iron, #germanium and #tellurium. This material is in the form of a thin sheet that is only a few to 10 #atoms in thickness. It is called a 2D #ferromagnet.
