1. Kev npaj ntub dej:

Hydrofluoric acid precipitation-vacuum dehydration method. Ntxiv cov hydrofluoric acid ntau dhau rau erbium chloride lossis erbium nitrate, thiab evaporate, mloog zoo, txias thiab crystallize cov kua dej ntawm cov dej da dej los npaj erbium trifluoride hydrate. Tom qab ntawd nws yog rhaub hauv lub tshuab nqus tsev kom tshem tawm cov dej crystallization.

2. Ammonium bifluoride fluorination txoj kev;

3. Kev npaj qhuav:

Nws yog tsim los ntawm reacting nrog anhydrous hydrogen fluoride gas thiab tsawg ntiaj teb oxides.

Nws yog siv rau optical txheej, kho qhov muag fiber ntau doping, laser siv lead ua, ib leeg siv lead ua raw khoom, laser amplifier, catalytic additive, npaj cov hlau erbium thiab alloy, thiab lwm yam.

Erbium fluoride nyias zaj duab xis siv lead ua

Hauv qhov chaw kho qhov muag, kev sib txuas lus kho qhov muag, spectrometers, lasers thiab lwm lub tshuab kho qhov muag loj, lub luag haujlwm ntawm cov yeeb yaj kiab kho qhov muag thiab cov khoom siv tseem ceeb heev. Nyob rau tib lub sijhawm, cov ntawv thov hauv cov teb no kuj tau tso ntau qhov kev xav tau nruj rau cov khoom siv kho qhov muag, lub cev thiab tshuaj lom neeg ntawm cov yeeb yaj kiab nyias nyias. Piv txwv li, nyob rau hauv cov khoom siv kho qhov muag, cov khoom siv txheej yuav tsum muaj qhov tsim nyog spectral kis tau tus mob thiab refractive index, thiab ib tug txaus me me nqus nyob rau hauv lub kis tau tus mob ntau yam. Nyob rau hauv cov nqe lus ntawm mechanical thiab tshuaj stability, cov ntaub ntawv txheej yuav tsum muaj cov khoom siv ruaj khov, tsis hnov ​​​​tsw rau ib puag ncig kev hloov pauv, tsis tshua muaj kev ntxhov siab sab hauv thiab ob peb qhov tsis xws luag. Nyob rau hauv cov ntaub ntawv infrared optical nyias zaj duab xis siv tam sim no, cov ntaub ntawv uas tuaj yeem ua tau raws li cov kev xav tau saum toj no raug txwv, tshwj xeeb tshaj yog nyob rau thaj tsam yoj ntev infrared, muaj tsawg dua qhov ruaj khov qis refractive index nyias zaj duab xis cov ntaub ntawv.

Lub ntiaj teb tsis tshua muaj fluoride yog cov khoom pob tshab zoo los ntawm lub tshuab nqus tsev ultraviolet mus rau thaj tsam deb infrared. Nyob rau hauv lub tshuab nqus tsev ultraviolet cheeb tsam, tsawg lub ntiaj teb fluoride yuav siv tau raws li ib tug siab refractive index txheej nyob rau hauv ultraviolet nyias zaj duab xis li, thaum nyob deb infrared cheeb tsam, tsis tshua muaj lub ntiaj teb fluoride kuj siv tau raws li ib tug tsawg refractive index txheej nyob rau hauv infrared nyias zaj duab xis. Nyob rau hauv xyoo tas los no, daim ntawv thov ntawm lub ntiaj teb tsis tshua muaj fluoride hauv lub tshuab nqus tsev ultraviolet optical nyias zaj duab xis cov cuab yeej tau nyiam cov neeg tshawb fawb ntau.

Erbium fluoride belongs rau lanthanide hnyav lub ntiaj teb fluoride. Cov kev tshawb fawb Pisarska qhia tau hais tias qhov infrared cutoff wavelength ntawm erbium fluoride iav tuaj yeem ncav cuag 21.74 ±0.05 μ m, uas yog siab dua li lwm cov iav fluoride. Cov txiaj ntsig tau pom tias erbium fluoride yog qhov muaj peev xwm ntev-yoj infrared qis refractive index pob tshab khoom.
