Isicelo:
ILanthanum Fluoride, isetyenziswe ngokukodwa kwiglasi ekhethekileyo, unyango lwamanzi kunye ne-catalyst, kunye neyona nto iphambili yokwenza i-Lanthanum Metal.ILanthanum Fluoride (LaF3) yinxalenye ebalulekileyo yeglasi yeFluoride enzima ebizwa ngokuba yiZBLAN.Le glasi ine-transmittance ephezulu kuluhlu lwe-infrared kwaye ngoko isetyenziselwa iinkqubo zonxibelelwano ze-fiber-optical.ILanthanum Fluoride isetyenziswa kwiingubo zesibane sephosphor.Ixutywe ne-Europium Fluoride, iphinda isetyenziswe kwi-crystal membrane ye-Fluoride ion-selective electrodes.I-Lanthanum fluoride isetyenziselwa ukulungisa i-scintillators kunye nezinto ezinqabileyo ze-crystal laser emhlabeni ezifunwa bubuchwephesha bokuboniswa komfanekiso wezonyango kunye nesayensi yenyukliya.ILanthanum fluoride isetyenziselwa ukwenza i-fluoride glass optical fiber kunye neglasi ye-infrared yomhlaba enqabileyo.ILanthanum fluoride isetyenziselwa ukuvelisa i-arc isibane se-carbon electrode kwimithombo yokukhanyisa.ILanthanum fluoride esetyenziswa kuhlalutyo lweekhemikhali ukwenza i-electrode ye-fluoride ion ekhethiweyo.

Indlela yokwenziwa
1. Dlulisa i-lanthanum oxide kwi-hydrochloric acid ngendlela yekhemikhali kwaye uhlambulule kwi-100-150g / L (ibalwa njengeLa2O3).Fudumeza isisombululo kwi-70-80 ℃, kwaye emva koko ugalele nge-48% ye-hydrofluoric acid.Imvula iyahlanjwa, ihluzwe, yomiswe, icolwe, kwaye ifunjwe ngamanzi ukuze ifumane i-lanthanum fluoride.
2. Faka isisombululo seLaCl3 esine-hydrochloric acid kwisitya seplatinum kwaye ungeze i-40% ye-hydrofluoric acid.Galela ulwelo olugqithisileyo kwaye ukhuphe intsalela yomile.
