Special Thread: Yanayojiri Mgogoro wa Ukraine na Urusi. Nini chanzo na hatma ya mzozo?

Tatizo mzee unaruka ruka hakuna rare earth metals Taiwan. Bali Taiwan wana vinu vya kutengeneza semiconductors. Go back to school

"Taiwan monazite is a unique mineral obtained from the heavy sand found in the river floor of Tzuo-suei river and En-suei river. Both rivers are flowing parallel with separated narrow area into the sea at southwestern coast of Taiwan. The characteristic of monazite is that it contains considerable rare earth elements (REEs)."

Unajua semicondutor ni nini ?
 
Leo utanikoma

The Bayan Obo mine located in the Inner Mongolia region of China is the world's biggest rare earth element (REE) mine both by recoverable reserves and production. It accounts for more than 40% of the total known REE reserves in the world and nearly half of the global rare earth production.

 
Tatizo mzee unaruka ruka hakuna rare earth metals Taiwan. Bali Taiwan wana vinu vya kutengeneza semiconductors. Go back to schoo

Correction: Taiwan produces almost 3/4 of the world's semiconductors.

Jesus Mlokozi Ni kweli hakuna rare earth metals Taiwan ?
 
Tatizo unakurupuka na una copy vitu ambavyo huvijui. Wewe unaongelea
Monazite is a rare phosphate mineral with a chemical composition of (Ce,La,Nd,Th)(PO4,SiO4).

But tunaongelea
The group consists of yttrium and the 15 lanthanide elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium).
Au hujui periodic table mwanangu. Nenda kasome Chemistry tena form one.
 
Mimi sio mjinga kama wewe ambaye hata ukikosea kwanza huwezi kugundua, kukiri ndiyo haiwezekani -- angalia correction yangu.

Umesema hakuna REEs Taiwan, ni kweli ?
 
Correction: Taiwan produces almost 3/4 of the world's semiconductors.

Mzee usihamishe magori. Semiconductor na Rare earth metals ni vitu viwili tofauti. Kwanza unatakiwa ukubali kwamba umepuyanga ndio niendelee kukutoa tongo tongo. Na vilevile usilete story za vijiweni kwa watu wasomi kama mimi.
 

Hii kutoka kwenye paper ni nini "it contains considerable rare earth elements (REEs)"

Nimesema semicondutors ni REEs ?
 

Kama tunalima ngano kinachotusibu kulilia ngano ya mrusi ni nini??
 

Point yako kwamba majimbo yanarudi Ukraine??.
 
Hiyo link uliyoleta inaongelea monazite ni element gani na ipo kwenye periodic table ipi!? Unajua maana ya Element lakini!?
Na unajua kirefu cha REE!?

Hivi wewe mbona una akili ya ajabu, naongelea kitu kilichoandikwa kwenye scientific paper ambayo ni published na reputable journal, unaelewa nini hapa:

"The characteristic of monazite is that it contains considerable rare earth elements (REEs). REEs are considered very useful elements in the local industries and scientific researches such as ceramic, semiconductors, and glass optics."

Naweka pia wikipedia:

"Monazite is a primarily reddish-brown phosphate mineral that contains rare-earth elements. Due to variability in composition, monazite is considered a group of minerals." - Monazite - Wikipedia
