Ntchito:

Lanthanum fwinoidedide, amagwiritsidwa ntchito makamaka mugalasi yapadera, chithandizo chamadzi ndi chothandizira, komanso monga zida zazikulu zopangira lantanham. Lanthanum fluoride (laf3) ndi gawo lofunikira lagalasi lolemera la zzaoride. Magalasi awa ali ndi mawonekedwe apamwamba mu mtundu wa infrator ndipo amagwiritsidwa ntchito ziwonetsero za fiber-mafinya. Lanthanum fluoride imagwiritsidwa ntchito mu phosphor nyali zofunda. Wosakanikirana ndi europium fluoride, imagwiritsidwanso ntchito mu nembanemba ya fluoride ya ictide ion - kusankha electrodes a eleoride ion-electrodes.lantheum fluoride amagwiritsidwa ntchito pokonzekera ukadaulo wamakono Lanthanum fluoride imagwiritsidwa ntchito kupanga fluoride galasi la galasi la galasi komanso galasi lopanda kanthu. Lanthanum fluoride imagwiritsidwa ntchito popanga ma arc nyali zamagetsi magwero owunikira. Lanthanum fluoride yogwiritsidwa ntchito popenda mankhwala kupanga fluoride ion kusankha electrodes.

Njira yopanga

1. Sungunulani lanthanum oxide mu hydrochloric acid ndi njira ya mankhwala ndikuchepetsa ma 100-150g / l (kuwerengetsa monga La2o3). Tenthetsani yankho la 70-80 ℃, kenako poyenda ndi 48% hydrofluoric acid. Kukhazikika kumatsukidwa, kusefedwa, zouma, zophwa, ndikupukuta, ndi vacuum, komanso kusokonezeka, ndikusita thupi kuti mupeze flantaum fluoride.

2. Ikani njira ya lacl3 yokhala ndi hydrochloric acid mu mbale ya platinamu ndikuwonjezera ma hydrofgoric acid. Thirani madzi ochulukirapo ndikusintha zotsalazo.
