ZnS yog ib qho tseem ceeb heev optical crystals siv nyob rau hauv IR waveband.
Kev xa tawm ntau ntawm CVD ZnS yog 8um-14um, siab transmittance, tsis tshua muaj nqus, ZnS nrog ntau qib spectrum los ntawm cua sov thiab lwm yam. static siab technics tau txhim kho qhov xa tawm ntawm IR thiab pom ntau yam.
Zinc Sulphide yog tsim los ntawm kev sib txuas los ntawm Zinc vapor thiab H2S gas, sib sau ua nplooj ntawv ntawm Graphite susceptors.Zinc Sulphide yog microcrystalline nyob rau hauv cov qauv, lub grain loj raug tswj los tsim lub zog siab tshaj plaws.Qib Multispectral yog tom qab ntawd Kub Isostatically Pressed (HIP) los txhim kho qhov nruab nrab IR kis tau tus mob thiab tsim daim ntawv pom tseeb.Ib leeg siv lead ua ZnS muaj, tab sis tsis muaj ntau.
Zinc Sulphide oxidizes heev ntawm 300 ° C, nthuav tawm cov yas deformation ntawm li 500 ° C thiab dissociates txog 700 ° C.Rau kev nyab xeeb, Zinc Sulphide windows yuav tsum tsis txhob siv siab tshaj 250 ° C nyob rau hauv ib txwm huab cua.
Daim ntawv thov: Optics, electronics, photoelectronic khoom siv.
