    ZnS yog qhov tseem ceeb heev kho qhov muag siv tau hauv IR waveband.
    Kev sib kis ntau ntawm CVD ZnS yog 8um-14um, qhov sib kis tau zoo, qis nqus, ZnS nrog ntau-spectrum qib los ntawm cua sov thiab lwm yam zoo li tus siab thev naus laus zis tau txhim kho transmittance ntawm IR thiab pom ntau yam.
    Zinc Sulphide yog tsim los ntawm kev sib txuas los ntawm Zinc vapor thiab H2S roj, sib sau ua cov ntawv ntawm Graphite susceptors. Zinc Sulphide yog microcrystalline hauv cov qauv, cov noob nplej loj tau tswj hwm kom tsim tau lub zog tshaj plaws. Multispectral qib yog tom qab ntawd Qhov Kub Hnyav Loj Sib Ntsuam (HIP) txhawm rau txhim kho qhov nruab nrab ntawm IR kis thiab ua daim ntawv pom tseeb. Ib leeg siv lead ua ZnS muaj, tab sis tsis sib xws.
    Zinc Sulphide oxidizes ntau txog 300 ° C, ua kom pom cov yas deformation ntawm kwv yees li 500 ° C thiab cuam tshuam txog 700 ° C. Kom muaj kev nyab xeeb, Zinc Sulphide lub qhov rais yuav tsum tsis txhob siv ntau dua 250 ° C hauv cov huab cua ib txwm muaj.
