Txoj kev npaj ntawm terbium fluoride:
Hydrofluoric acid yog ntxiv rau cov tshuaj terbium aqueous, los yog terbium hydroxide Tb (OH) 3 yog reacted nrog hydrofluoric acid los npaj hydrated terbium fluoride, thiab tom qab ntawd cov dej crystallization raug tshem tawm los ntawm cua sov hauv lub tshuab nqus tsev.
Qhov concentration ntawm hydrofluoric acid feem ntau yog 40% ~ 48%, thiab nws qhov kev noj yog 110% ~ 120% ntawm qhov theoretical npaum li cas. Lub terbium fluoride precipitate precipitated los ntawm aqueous tov yuav tsum tau ntxuav tag nrho nrog dej, thiab cov txheej txheem pouring yog siv rau cov dej ntxuav. Cov dej lim dej tau qhuav ntawm 100 ~ 150 degree kom tshem tawm cov dej adsorbed. Fluoride uas muaj cov dej siv lead ua nkaus xwb tau txais. Txhawm rau kom tsis txhob kub siab hydrolysis thaum lub caij lub cev qhuav dej thiab tsim cov oxyfluoride TbOF, cov txheej txheem lub cev qhuav dej yuav tsum tau ua kom sov hauv lub tshuab nqus tsev. Lub tshuab nqus tsev kawm ntawv yuav tsum siab tshaj 0.133Pa, thiab lub cev qhuav dej kub yuav tsum tsis txhob qis dua 300 degree.
Lwm txoj kev lub cev qhuav dej yog dehydrate hydrated terbium fluoride nyob rau hauv qhuav hydrogen fluoride gas ntws. Qhov kawg lub cev qhuav dej kub yog 600 ~ 650 degree. Txoj kev ua kom lub cev qhuav dej no nyob rau hauv kev tiv thaiv ntawm hydrogen fluoride cua tuaj yeem ntxiv fluoride hydrated terbium fluoride thaum lub caij lub cev qhuav dej, ua kom cov khoom zoo. Txij li thaum hydrofluoric acid nag lossis daus yog nqa tawm hauv cov kua dej, cov ntim yas feem ntau yog siv, thiab cov khoom siv ntawm lub cev qhuav dej yuav tsum tiv taus kub kub corrosion. Nickel-based alloys lossis npib tsib xee ntshiab feem ntau yog siv los ua cov ntaub ntawv hauv ob sab phlu.
Kev siv terbium fluoride:
Nws yog tsuas yog siv rau kev npaj ntawm metallic terbium, magnetostrictive cov ntaub ntawv, optical fiber doping, laser cov ntaub ntawv, kuaj reagents, additives rau ceramics thiab coatings, npaj cov ntaub ntawv roj teeb, thiab iav corrosion inhibitors.
Terbium fluoride kuj tseem siv tau rau cov kab ciam diffusion hauv sintered NdFeB hlau nplaum.
Kev siv tshwj xeeb ntawm terbium fluoride:
1. Cov ntawv thov kho qhov muag: Terbium fluoride muaj qhov ntsuas siab siab thiab pob tshab, yog li nws tuaj yeem siv los npaj cov ntaub ntawv qhov rai rau cov iav kho qhov muag, kho qhov muag fibers thiab lasers.
2. Nuclear zog daim ntaub ntawv: Lub fission hla ntu ntawm terbium-159 isotope yog me me, yog li terbium fluoride yog siv los ua cov khoom siv neutron hauv kev lag luam nuclear.
3. Raws li cov catalyst: Raws li cov oxidant muaj zog, terbium fluoride tuaj yeem siv los ua cov catalyst hauv cov organic synthesis, xws li oxidation, hydrogenation thiab rearrangement tshua.
4. Cov khoom siv hluav taws xob: Terbium fluoride muaj cov khoom siv hluav taws xob zoo thiab tshuaj lom neeg ruaj khov thiab tuaj yeem siv los npaj cov khoom siv hluav taws xob kub kub, cov khoom siv hluav taws xob semiconductor thiab cov khoom siv electrolyte.
