Kev siv tshwj xeeb ntawm terbium fluoride:
Dysprosium fluoride tuaj yeem tsim los ntawm dysprosium trioxide thiab hydrofluoric acid. Sib tov dysprosium oxide thiab ammonium bifluoride thiab kub rau 300 degree kom cov oxide ntxeem tau. Txuas ntxiv nce qhov kub ntawm 700 degree. Thaum siv hydrogen fluoride, cov tshuaj tiv thaiv yuav tshwm sim:
Dy2O3 + 6 HF → 2 DyF3 + 3 H2O
Dysprosium fluoride kuj tuaj yeem tau txais los ntawm reacting DyCl3 los yog Dy2 (CO3)3 nrog 40% hydrofluoric acid:
DyCl3 + 3 HF → DyF3↓ + 3 HCl
Dy2(CO3)3 + 6 HF → 2 DyF3 + 3 H2O + 3 CO2↑
DyF3 tseem tuaj yeem tsim los ntawm hydrothermal cov tshuaj tiv thaiv ntawm dysprosium nitrate thiab sodium fluoroborate ntawm 200 degree.
Kev siv dysprosium fluoride:
Nws yog siv los npaj cov hlau dysprosium, magnetostrictive cov ntaub ntawv, optical fiber doping, laser cov ntaub ntawv, kuaj reagents, thiab lwm yam. Dysprosium fluoride muaj ib tug siab melting point thiab siab hardness, yog li nws yog feem ntau siv raws li ib tug additive nyob rau hauv ceramic cov ntaub ntawv thiab coatings.
Dysprosium fluoride kuj tseem siv tau rau cov nplej ciam diffusion ntawm sintered NdFeB hlau nplaum. Ib txoj hauv kev ua qhov no yog raws li hauv qab no:
Ua ntej, tsis tshua muaj lub ntiaj teb nano-sib tov hmoov xws li dysprosium fluoride thiab terbium ntxiv rau NdFeB raw khoom hmoov thiab sib tov sib npaug. Tom qab ntawd cov hmoov sib tov sib xyaw yog taw qhia nyob rau hauv ib qho chaw sib nqus thiab nias los ua ib qho kev cog lus; Tom qab ntawd lub compact yog muab tso rau hauv lub tshuab nqus tsev sintering rauv rau dehydrogenation thiab sintering txheej txheem; thiab thaum kawg kev kho cua sov yog nqa tawm.
Sintered NdFeB sib nqus cov ntaub ntawv nrog ob qho tib si siab coercivity thiab zoo heev sib nqus zog yog npaj los ntawm kev hloov cov ntshiab hnyav tsis tshua muaj ntiaj teb terbium los yog dysprosium nanoparticles nrog tsawg ntiaj teb nanomixed hmoov hais xws li dysprosium fluoride thiab terbium. Piv nrog rau cov ntshiab hnyav tsis tshua muaj hauv ntiaj teb nanopowder hais, nanopowder hais ntawm lub ntiaj teb tsis tshua muaj fluorides xws li dysprosium fluoride thiab terbium tsis yooj yim oxidized, thiab cov ntsiab lus ntawm cov pa oxygen thaum lub sij hawm npaj cov hlau nplaum raug txo kom tsawg. High-performance sintered hlau nplaum tuaj yeem npaj siv cov khoom siv tsoos.
