Tantalum tshwm sim nyob rau hauv cov ntxhia columbite-tantalite. Nws yog feem ntau pom nyob rau hauv Australia , Brazil , Mozambique, Thaib, Portugal, Nigeria, Zaire thiab Canada . Sib cais tantalum los ntawm niobium yuav tsum tau electrolysis, txo cov poov tshuaj fluorotantalate nrog sodium los yog reacting carbide nrog oxide.
Tib neeg kuj nug, qhov twg tantalum feem ntau pom nyob rau hauv lub ntiaj teb?
Qhov tshwm sim nyob rau hauv qhov Lub ntsiab yog feem ntau pom nyob rau hauv Cov zaub mov muaj xws li tantalite, microlite thiab tantalite. Nws ib txwm tshwm sim nrog niobium . Tsuas yog qhov chaw ntawm tantalum hauv North America yog kuv li nyob ntawm Bernic Lake hauv xeev Manitoba hauv Canada.
Qhov thib ob, dab tsi muaj tantalum? Tus thawj tantalum ore yog tantalite, uas kuj muaj hlau, manganese thiab niobium, thiab samarskite, uas muaj xya metal. Lwm ore uas muaj tantalum thiab niobium yog pyrochlore. Cov chaw mining tseem ceeb yog Thaib teb, Australia, Congo, Brazil, Portigal thiab Canada.
Hais txog qhov no, qhov twg tantalum siv?
Tantalum yog siv nyob rau hauv electronics kev lag luam rau capacitors thiab siab zog resistors. Nws kuj yog siv ua alloys kom muaj zog, ductility thiab corrosion kuj. Cov hlau yog siv nyob rau hauv kev kho hniav thiab phais cov cuab yeej thiab implants, raws li nws ua rau tsis muaj kev tiv thaiv kab mob.
Leej twg muaj tantalum tshaj plaws?
Rwanda yog lub ntiaj teb coob tus tsim khoom ntawm tantalum , ib qho tseem ceeb ntxhia rau cov khoom siv hluav taws xob. Raws li cov ntaub ntawv tshaj tawm Mineral Commodity Summaries, Rwanda tsim ib ncig 37 feem pua ntawm lub ntiaj teb. tantalum kev xa khoom hauv xyoo 2015, thaum DR Congo suav txog 32 feem pua ntawm cov khoom ntxiv.

Qhov chaw nyob ntawm lub cev thiab qhov chaw nyob qhov chaw nyob yog dab tsi?
Qhov sib txawv yooj yim ntawm Logical thiab lub cev chaw nyob yog qhov chaw nyob Logical yog tsim los ntawm CPU hauv kev xav ntawm ib qho kev pab cuam. Ntawm qhov tod tes, qhov chaw nyob ntawm lub cev yog qhov chaw nyob uas muaj nyob hauv lub cim xeeb. Cov txheej txheem ntawm txhua qhov chaw nyob uas tsim los ntawm CPU fora program hu ua Logical Address Space
Lub ntsiab lus dab tsi feem ntau pom nyob rau hauv daim duab ncuav qab zib?
Ib qho piv txwv lossis cov lus piav qhia ntawm daim ntawv qhia ncuav qab zib yog feem pua. Qhov laj thawj yog tias feem pua yog muab los ua ib feem ntawm tag nrho (100%). Daim duab ncuav qab zib yog siv los saib seb tus kheej li cas piv rau tag nrho, yog li feem pua yog feem ntau siv los qhia qhov no
