Chikumbiro:
Lanthanum Froride, inonyanya kuiswa muGlassy Girazi, kurapwa kwemvura uye kuipa, uye zvakare seyakagadzirwa zvinhu zvekushandisa zvekugadzira lanthanum. Lanthanum Fluoride (LAF3) Chinhu chakakosha chikamu chegirazi rinorema fluoride girazi rainzi Zblan. Iyi girazi ine yepamusoro inodengenyeka muInfrared range uye saka inoshandiswa kune fiber-Optical kutaurirana masisitimu. Lanthanum Fluoride inoshandiswa muPosphor Lamp Coatings. Yakavhenganiswa neEuropide Froride, inoiswawo muCyrstal membrane yeFluoride IIon.lanthanum Florides. Lanthanum Fluoride inoshandiswa kugadzira fluoride girazi remagetsi enzi uye risingawanzo nyika infrared girazi. Lanthanum Fluoride inoshandiswa mukugadzira arc mwenje weARC magetsi efaira electrodes mune mwenje. Lanthanum Fluoride inoshandiswa mukuongororwa kwemakemikari kuti agadzire fluoride ion anosarudza electrodes.

Synthetic nzira
1. Dissolve Lanthanum oxide muHydrochloric acid neCemical Nzira uye Dilute kuenda ku100-150G / L (yakaverengerwa seLA2O3). Pisa mhinduro ye 70-80 ℃, uye wozoperekedza ne 48% hydrofluorgic acid. Precipation yakashambidzwa, yakasviba, yakaoma, yakapwanywa, uye vacuum yakadzvanywa kuti vawane lanthanum fluoride.
2. Isa LACL3 Solution ine hydrochloric acid mune platinum mundiro uye wedzera 40% hydrofluor acid acid. Durura mvura yakawandisa uye inobvisa zvakasara yakaoma yakaoma.
