I-ZnS iyikristalu ebonakalayo ebaluleke kakhulu esetshenziswa ku-IR waveband.
Ububanzi bokudlulisa be-CVD ZnS ngu-8um-14um, ukudluliswa okuphezulu, ukumuncwa okuphansi, i-ZnS enezinga le-multi-spectrum ngokushisa njll. Ubuchwepheshe be-static pressure buthuthukise ukudluliswa kwe-IR kanye nobubanzi obubonakalayo.
I-Zinc Sulphide ikhiqizwa yi-synthesis evela ku-Zinc vapor kanye ne-H2Igesi ye-S, eyakha njengamashidi kuma-Graphite susceptors.I-Zinc Sulphide iyi-microcrystalline ngesakhiwo, usayizi wokusanhlamvu ulawulwa ukukhiqiza amandla aphezulu.Ibanga le-Multispectral libe seliba I-Hot Isostatically Pressed (HIP) ukuze kuthuthukiswe ukudluliswa kwe-IR emaphakathi futhi kukhiqizwe ifomu elisobala elicacile.I-Single crystal ZnS iyatholakala, kodwa ayivamile.
I-Zinc Sulphide i-oxidize kakhulu ku-300°C, ikhombisa ukuguga kwepulasitiki cishe ku-500°C futhi ihlukanisa cishe no-700°C.Ukuze uphephe, amafasitela eZinc Sulphide akufanele asetshenziswe ngaphezu kuka-250°C endaweni evamile.
