Quartz iav yog tsim los ntawm melting ntau yam ntshiab ntuj quartz.

Nws cov coefficient ntawm thermal expansion yog tsawg kawg nkaus, tsuas yog 1/10 txog ntawm lub khob dog dig, thiab nws muaj cov cua sov zoo heev. Nws tseem muaj kub kub - tiv taus, nrog ib txwm ua haujlwm ntawm 1100℃thiab luv {8} {{xyoo ua haujlwm kub txog 1400 degree.

Quartz iav yog feem ntau siv nyob rau hauv cov khoom siv kuaj thiab hauv kev ua kom zoo dua ntawm cov khoom lag luam tshwj xeeb. Nws lub siab hloov pauv ua rau nws lub cev tiv thaiv hluav taws xob puas tsuaj (lwm qhov tsom iav ua kom zoo nkauj thaum muaj qhov rai
Quartz iav yog qhov tshwj xeeb iav tsim ib leeg ntawm silicon dioxide. Nws muaj lub siab tawv, ncav tau MoHs 7, thiab nta siab {{2} kub heev, cov tshuaj lom neeg ruaj khov, thiab hluav taws xob hluav taws xob, thiab hluav taws xob hluav taws xob rwb thaiv tsev.

Nws yog pob tshab rau ultraviolet thiab infrared rays. Nws ua cov yeeb yam zoo acid tiv taus rau cov acids, muaj kev zam ntawm hydrofluoric acid thiab kub phosphoric acid. Nws tau cais los ntawm pob tshab rau hauv ob pawg: pob tshab thiab opaque. Purity tau muab faib ua peb pawg: siab- purity, dog dig, thiab doped. Nws yog tsim los ntawm siv lead ua, silica, thiab cov kab muag kom huv los ntawm kev kub siab- kub yaj lossis tshuaj vapor deposition. Lub hau txav melting muaj suav nrog hluav taws xob melting thiab roj refining.

Muaj ntau hom fused silica siv rau daim ntawv thov sib txawv. Peb feem ntau muaj peb hom, suav nrog JGS1, JGS2, JGS3

JGS1 (Far UV Optical Quartz iav)Nws yog lub quartz iav ua los ntawm cov khoom siv hluavtaws nrog Sicl 4 li cov khoom siv raw thiab melted los ntawm kev ua siab purame. Yog li nws muaj ntau npaum li cas ntawm hydroxyl (ib ncig ntawm 2000 ppm) thiab muaj kev sib kis UV zoo tshaj plaws. Tshwj xeeb tshaj yog nyob rau hauv lub luv luv UV cheeb tsam, nws qhov kev xa tawm tau zoo dua li lwm yam iav. Tus nqi thauj UV ntawm 185nm tuaj yeem ncav cuag 90% lossis ntau dua. Lub Synthetic Quartz iav tau txais cov txiaj ntsig zoo heev ntawm 2730 NM thiab tsis muaj cov qauv sib txawv. Nws yog cov khoom siv kho kom zoo tshaj plaws nyob rau hauv ntau yam ntawm 185 - 2500nm. JGS1 yog siv rau optics ua haujlwm hauv UV UV thiab pom wavelength, lo ntsiab muag, prisms, prisms thiab lwm yam nws yog kev siv dawb ntawm npuas thiab suav nrog. JGS1 fused silica yog similiariariariariary Heraeus - Supasil 1 thiab Gorrosus - Specting's 7980 Dynasil 1100 thiab 4100.

JGS2 (UV Optical Quartz iav)
Nws yog Quartz iav ua los ntawm cov roj refining nrog siv lead ua li cov khoom siv raw, muaj ntau ntau ntawm ppm hlau impurities. Muaj cov ntsiab lus nqus tau (hydroxyl cov ntsiab lus 100-200ppm) ntawm 2730nm, nrog stripe thiab qauv qauv. Nws yog cov khoom siv zoo nyob rau hauv lub nthwv dej yoj ntau ntawm 220-2500 nm. Cov txiaj ntsig muaj xws li UV thiab pom tau zoo ib yam li JGS1. Tuaj yeem ua rau hauv cov kab mob vwm me me / qhov loj me uas tuaj yeem ua tau zoo heev thiab yog pub dawb ntawm npuas. Cons suav nrog cov npuas muaj peev xwm loj hauv qhov loj me / diameters.

JGS2 Fused Silica yog similiariariariar rau cov chaw tsim khoom hauv qab no
Heraeus 'Homosil 1,2; 3
Dynasil 1000; 4000; 5000; 6000

Cov ntawv thov rau JGS2 suav nrog:

condenser optics;Kev kub siab thiab siab li qub

flatical flats;Lub tshuab tsom me me swb;Pom tsom iav

3. ((infrared kho qhov muag quartz iav) jgs3

JGS3 yog pob tshab hauv Ultraviolet, pom thiab infrared spectral spructions. Nws yog qhov nqus cov hlua ua tau nyob hauv 185 - 250 nm spectral cov yam ntxwv hauv UV UV thiab cov merr yoj. Nws yog cov uas yuav tsum tau ua wavelength heev los ntawm Luv mus mir. Nws yog me ntsis kim dua li silicon thiab me ntsis tsis kim tshaj calcium fluoride lossis Zns ntau qib kev qhia.JGS3 yog similiariar rau cov neeg tsim khoom hauv qab no Heraeus Suprasil 300.
