    ZnSe yog ib hom daj thiab pob tshab mulit-cystal cov ntaub ntawv, qhov loj ntawm crystalline particle yog hais txog 70um, kis ntau yam ntawm 0.6-21um yog ib qho kev xaiv zoo heev rau ntau yam IR daim ntaub ntawv nrog rau siab zog CO2 laser tshuab.
    Zinc Selenide muaj tsawg IR nqus.Qhov no yog qhov zoo rau kev ntsuas thermal, qhov twg qhov kub ntawm cov khoom tej thaj chaw deb tau txheeb xyuas los ntawm lawv cov blackbody hluav taws xob spectrum.Ntev wavelength transparency yog ib qho tseem ceeb rau kev ntsuam xyuas cov khoom kub hauv chav tsev, uas radiate ntawm lub ncov wavelength ntawm kwv yees li 10 μm nrog tsawg heev siv.
    ZnSe muaj qhov ntsuas siab ntawm refraction uas yuav tsum muaj cov txheej txheem tiv thaiv kev cuam tshuam kom ua tiav kev sib kis siab.Peb broadband AR txheej yog optimized rau 3 μm rau 12 μm.
    Znse cov khoom ua los ntawm cov tshuaj vapor deposition (CVD) yeej tsis muaj impurity absorption, tawg puas tsuaj tsawg heev.Vim tias lub teeb pom kev tsawg heev rau 10.6um wavelength, yog li ZnSe yog thawj cov khoom siv los ua cov khoom siv kho qhov muag ntawm lub zog siab Co2 laser system.Tsis tas li ntawd, ZnSe tseem yog ib hom khoom siv rau kev sib txawv ntawm qhov muag pom hauv tag nrho cov kev xa tawm waveband.
    Zinc Selenide yog tsim los ntawm kev sib txuas los ntawm Zinc vapor thiab H2Se roj, tsim los ua cov ntawv ntawm Graphite susceptors.Zinc Selenide yog microcrystalline nyob rau hauv cov qauv, lub grain loj raug tswj los tsim lub zog siab tshaj plaws.Ib leeg siv lead ua ZnSe muaj, tab sis tsis muaj ntau tab sis tau tshaj tawm tias muaj kev nqus qis dua thiab yog li ua tau zoo dua rau CO2 optics.

    Zinc Selenide oxidizes heev ntawm 300 ° C, nthuav tawm cov yas deformation ntawm li 500 ° C thiab dissociates txog 700 ° C.Rau kev nyab xeeb, Zinc Selenide qhov rais yuav tsum tsis txhob siv siab tshaj 250 ° C nyob rau hauv ib txwm huab cua.
