Meatotino Faaletino ma Vailaau Lithium fluoride o le paʻepaʻe paʻepaʻe, sodium chloride ituaiga fausaga tioata. Tulaga va'aiga 2.640, liusuavai 848 ℃, fa'apuna 1673 ℃. I le 1100 ~ 1200 tikeri na amata ona faʻafefe, o le ausa e alkaline. Lithium fluoride e solu teisi i le vai ma e le mafai ona solu i le ava malosi ma isi solvents organic. I le vevela o le potu, e soluble Lithium fluoride i le nitric acid ma le sulfuric acid, ae le mafai ona solu i le hydrochloric acid, ma le hydrofluoric acid Li2HF acid salt formation.
Fa'aoga Faʻaaogaina e fai ma faʻaopoopoga mo le eletise alumini ma le eletise eletise e le masani ai, gaosiga tioata tioata, desiccant, flux, ma isi.

Folasaga

O loʻo taua i lalo se faʻamatalaga i meatotino, faʻaoga, metotia sauniuni ma faʻamatalaga saogalemu o le lithium fluoride:

 

Tulaga lelei:

1. Lithium fluoride o se tioata paepae pa'epa'e, leai se manogi ma le tofo.

3. Solu teisi i le vai, ae solu i le ava malosi, acids ma faavae.

4. E patino i tioata ionic, ma lona fausaga tioata o le tino- totonugalemu pusa.

 

Fa'aaogā:

1. Lithium fluoride e masani ona faʻaaogaina e fai ma faʻafefe mo metala e pei ole alumini, magnesium, ma le uʻamea.

2. I vaega faaniukilia ma aerospace, o le lithium fluoride o loʻo faʻaaogaina e fai ma meafaitino mo le gaosiga o suauʻu reactor ma lau afi afi mo afi afi.

3. Lithium fluoride o loʻo i ai le maualuga o le vevela o le liusuavai, ma e faʻaaogaina foi e fai ma faʻafefe i tioata ma ceramics.

4. I le fanua o maa, o le lithium fluoride o se mea taua tele mo le gaosiga o maa lithium-ion.

 

Metotia:

Lithium fluoride e masani ona saunia i auala nei e lua:

1. Hydrofluoric acid metotia: hydrofluoric acid ma lithium hydroxide o loʻo faʻaalia e gaosia ai le lithium fluoride ma le vai.

2. auala fa'a'ele'ele'ele'ele: fa'afefeteina le fa'afefete e tu'uina atu i le vaifofo lithium hydroxide e fa'atupu ai le fa'alili lithium ma le vai.

 

Fa'amatalaga Saogalemu:

1. Lithium fluoride o se mea pala e i ai se aafiaga ita i luga o le paʻu ma mata, ma e tatau ona aloese mai le faʻaaogaina.

2. Pe a tagofia le lithium fluoride, e tatau ona ofuina totigilima ma mata tioata talafeagai e puipuia ai faʻalavelave faʻafuaseʻi.

3. Lithium fluoride e tatau ona fa'amama ese mai fa'apogai fa'amumu ma fa'ama'i e 'alofia ai le mu po'o le pa.
