Isicelo:

I-Lanthanam ye-Lantharide, isetyenziswa ikakhulu kwiglasi eyodwa, unyango lwamanzi kunye ne-catalyst, kwaye njengezixhobo eziphambili ze-lanthanum. I-Lanthanam ye-Lantharide (I-LAF3) yinto ebalulekileyo kwiglasi enkulu eninzi ebizwa ngokuba yi-zblan. Le glass inezinto eziphezulu zokudluliselwa koluhlu olungena nzulu kwaye ke isetyenziselwa iinkqubo zonxibelelwano zefayibha. I-Lanthanam isetyenziswa kwi-phosphor semp yokudlala. Ixutywe ne-Europium Buleoride, ikwasetyenziswa kwi-crystal membrane ye-fluoride ye-ilrodes i-Electrodes.lanthalum isetyenziselwa ukulungiselela i-screstators ye-crystal ye-crystal ye-crystal ebonakalayo kunye nenzululwazi yenyukliya. I-Lanthanam isetyenziselwa ukwenza i-fluoride yefible yefibre kunye neglasi enqabileyo yeglasi. I-Lanthanam isetyenziswa kwimveliso ye-Arc Lamp yekhabhoni kwimithombo yokukhanya. I-Lanthanam isetyenziswa kuhlalutyo lweekhemikhali ukwenza i-fluoride ion ye-electrodes.

Indlela yokwenziwa

I-1. Dibanisa i-lanthanum oxide kwi-hydrochloric acid ngendlela yekhemikhali kunye ne-tilute ukuya kwi-100-150g / l (ibaliwe njenge-LA2O3). Fudumeza isisombululo kwi-70-80 ℃, kwaye emva koko cwangcise ngama-48% hydrofluoric acid. Uvavanyo luhlanjwa, luhlaselwe, lulomile, luphanzisiwe, kwaye luphelelwe ngumzimba ukuze ufumane i-lanthanum fluoride.

2. Beka isisombululo se-lacl3 esine-hydrochloric acid kwisitya seplatinam kwaye songeze i-40% hydrofluoric acid. Galela ulwelo olugqithisileyo kwaye luphuma kwintsalela eyomileyo.
