Cesium Chloride (CsCl2)
Txoj kev npaj
Kev npaj ua lag luam feem ntau yog los ntawm cov hauv qab no:
1. Kev sib xyaw ntawm cov hlau cesium nrog hydrochloric acid
2. Txoj kev ua kom tsis muaj zog nrog cesium carbonate lossis cesium hydroxide:
3. Kev rho tawm cov ntxhia: CsCl uas muaj purity siab tau txais los ntawm cov kuab paug los ntawm kev rho cov kua qaub, kev pauv pauv ion thiab lwm yam kauj ruam.
Cov khoom siv tshuaj lom neeg thiab lub cev
Cov tshuaj uas muaj zog heev: Qhov ceev ntawm cov kua CsCl uas saturated tuaj yeem ncav cuag 1.9 g / cm³, uas feem ntau siv rau kev sib cais ntawm cov qauv tshuaj lom neeg (xws li DNA purification).
Kev coj ua ntawm ionic: Molten CsCl yog ib qho ion conductor zoo heev thiab siv rau kev tshawb fawb electrolyte kub siab.
Cov khoom siv kho qhov muag: Cov siv lead ua CsCl muaj ntau lub teeb kis tau dav (0.2 ~ 55 μm) thiab siv tau rau cov khoom siv infrared spectrometer prisms.
Cov ntawv thov radioactive: Cov khoom siv gamma-ray ntawm Cs-137 ** (ib nrab-lub neej 30.17 xyoo) yog siv dav hauv kev kho mob thiab kev lag luam irradiation.
Cov ntawv thov tseem ceeb
1. Kev kawm txog lub cev:
Kev siv centrifugation gradient density yog siv los cais cov nucleic acids thiab cov kab mob me me.
Ua ib qho khoom siv buffer rau PCR cov tshuaj tiv thaiv.
2. Kev kho mob nuclear:
Cs-131 (ib nrab ntawm lub neej 9.7 hnub) yog siv rau kev kho mob brachytherapy ntawm mob qog nqaij hlav prostate.
3. Kev tshawb fawb txog cov ntaub ntawv:
Kev npaj cov cesium vapor rau cov raj photoelectric thiab cov ion thrusters.
Kev tsim cov khoom siv ua haujlwm nrog CsCl-hom qauv (xws li perovskite solar cell precursors).
Kev tshawb fawb yooj yim
Siv los npaj cov lattices optical hauv ultracold atom experiments.
Kawm txog tus cwj pwm hloov pauv theem ntawm cov ionic crystals (hloov mus ua NaCl-hom qauv ntawm qhov kub siab).
Kev Nyab Xeeb thiab Kev Khaws Cia
CsCl muaj tshuaj lom nruab nrab (LD₅₀ nas noj qhov ncauj yog li 2300 mg / kg), tab sis cov isotopes radioactive yuav tsum tau tiv thaiv nruj me ntsis. Kev khaws cia yuav tsum tsis txhob ntub thiab kaw kom tsis txhob kov cov oxidants muaj zog. Cov ntaub ntawv radioactive xws li Cs-137 yuav tsum tau tswj hwm raws li cov cai kev nyab xeeb nuclear.
Xaus lus
Vim nws cov qauv siv lead ua tshwj xeeb, kev yaj zoo heev thiab ntau yam isotopic yam ntxwv, cesium chloride muaj lub luag haujlwm tseem ceeb hauv kev tshawb fawb txog lub neej, kev siv tshuab nuclear thiab cov ntaub ntawv ua haujlwm. Nws cov ntawv thov txuas ntxiv mus rau kev tshawb fawb yooj yim mus rau kev siv tshuab siab, uas qhia txog tus nqi ntau yam ntawm alkali hlau halides.
