Uraninite, yav tas los pitchblende, yog cov xov tooj cua, uranium-nplua nuj ntxhia thiab ore nrog cov tshuaj muaj pes tsawg leeg uas yog UO 2 tab sis vim oxidation feem ntau muaj qhov sib txawv ntawm U 3O8. … Radioactive decay ntawm uranium ua rau cov pob zeb hauv av muaj oxides ntawm cov hlau lead thiab cov kab ntawm helium.
Pitchblende ua uraninite thaum twg?
Pitchblende, tom qab hloov npe hu ua uraninite (vim muaj uranium), tau tshawb pom thaum ntxov li 15th caug xyoo hauv cov nyiaj mines ze ntawm Czech / German ciam teb, tab sis nws muaj. siv tsawg heev thaum lub sijhawm, tshwj tsis yog tus neeg sawv cev uas hloov cov ceramics thiab iav xim daj-ntsuab.
YPuas yog uranium yog ib lub suab sib xyaw?
Pitchblende yog ib lub xov tooj cua, uranium-nplua nuj ntxhia thiab ore . Nws muaj cov tshuaj muaj pes tsawg leeg uas yog UO2, tab sis kuj muaj UO3 thiab oxides ntawm txhuas, thorium, thiab cov ntsiab lus tsis tshua muaj ntiaj teb. Nws yog lub npe hu ua pitchblende vim nws cov xim dub thiab siab ceev.
Uraninite yog dab tsi?
Uraninite, a loj ore ntxhia ntawm uranium, uranium dioxide (UO2). Uraninite feem ntau tsim cov xim dub, grey, lossis xim av uas muaj zog me ntsis thiab feem ntau opaque. Ntau hom uraninite ore uas tuab thiab pom nyob rau hauv granular masses nrog greasy luster hu ua pitchblende.
Puas yog pitchblende ib ore ntawm plutonium?
ABSTRACT Plutonium muajtau tshuaj lom neeg cais los ntawm xya qhov sib txawv thiab qhov piv ntawm plutonium rau uranium txiav txim siab. Qhov sib piv no tau pom tias muaj qhov tsis sib xws hauv pitchblende thiab monazite ores, uas cov ntsiab lus uranium txawv ntawm 50% mus rau 0.24%, thiab tsawg dua hauv carnotite thiab fergusonite.
