Silicon (Si)
Silicon muaj xim xiav-grey. Nws muaj qhov siab tshaj plaws kis tau tus mob ntawm 3 - 5 µm tshaj qhov kev sib kis tag nrho ntawm 1.2 - 8 µm. Vim muaj thermal conductivity thiab tsis tshua muaj siab, nws yog haum rau laser iav thiab optical lim. Loj blocks ntawm silicon nrog polished nto kuj ua hauj lwm raws li neutron lub hom phiaj nyob rau hauv physics thwmsim. Si yog cov khoom siv uas tsis tshua muaj nqi thiab lub teeb yuag, nws tsis tshua ntom dua Ge lossis ZnSe & muaj qhov ntom ntom zoo sib xws rau cov iav kho qhov muag, yog li nws tuaj yeem siv rau qee qhov xwm txheej qhov hnyav yog qhov kev txhawj xeeb. AR txheej yog pom zoo rau feem ntau daim ntawv thov. Silicon yog zus los ntawm Czochralski rub cov tswv yim (CZ) thiab muaj qee cov pa oxygen uas ua rau muaj zog nqus ntawm 9 µm, yog li nws tsis haum rau siv nrog CO2laser kis tau tus mob daim ntawv thov. Txhawm rau zam qhov no, Silicon tuaj yeem npaj los ntawm Float-Zone (FZ) txheej txheem.
