Noi:
Lanthanum Fluoride, Hoʻohana nui ʻia i ke aniani kūikawā, ka mālama ʻana i ka wai a me ka catalyst, a ʻo ia hoʻi nā kumu kumu nui no ka hana ʻana i ka Lanthanum Metal.ʻO ka Lanthanum Fluoride (LaF3) kahi mea nui o ke aniani Fluoride kaumaha i kapa ʻia ʻo ZBLAN.ʻOi aku ka maikaʻi o ka transmittance o kēia aniani i ka laulā infrared a no laila ua hoʻohana ʻia no nā ʻōnaehana kamaʻilio fiber-optical.Hoʻohana ʻia ʻo Lanthanum Fluoride i nā uhi kukui phosphor.Hoʻohui ʻia me ka Europium Fluoride, ua hoʻopili ʻia i ka membrane aniani o nā electrodes koho koho Fluoride.Hoʻohana ʻia ʻo Lanthanum fluoride no ka hoʻomākaukau ʻana i nā scintillators a me nā mea laser crystal crystal earth i koi ʻia e ka ʻenehana hōʻike kiʻi olakino hou a me ka ʻepekema nuklea.Hoʻohana ʻia ʻo Lanthanum fluoride e hana i ke aniani fluoride fiber optical fiber a me ke aniani infrared earth rare.Hoʻohana ʻia ʻo Lanthanum fluoride i ka hana ʻana i nā kukui arc carbon electrodes i nā kumu kukui.Hoʻohana ʻia ʻo Lanthanum fluoride i ka nānā ʻana kemika e hana i nā electrodes koho ion fluoride.

ʻano hana synthetic
1. E hoʻoheheʻe i ka lanthanum oxide i loko o ka waikawa hydrochloric ma ke ʻano kemika a dilute i 100-150g/L (helu ʻia ʻo La2O3).E hoʻomehana i ka hopena i 70-80 ℃, a laila e hoʻokahe me 48% hydrofluoric acid.Holoi ʻia ka ua, kānana ʻia, hoʻomaloʻo ʻia, ʻokiʻoki ʻia, a hoʻomaʻemaʻe ʻia ka wai e loaʻa ai ka lanthanum fluoride.
2. E kau i ka solution LaCl3 me ka waika hydrochloric i loko o ka ipu platinum a e hookomo i ka waika hydrofluoric 40%.E ninini i ka wai nui a e hoʻokahe i ke koena maloʻo.
