IiPropati zoMzimba kunye nezeMichiza I-Lithium fluoride ngumgubo omhlophe, i-sodium chloride uhlobo lwesakhiwo sekristale. Uxinzelelo olunxulumeneyo 2.640, indawo yokunyibilika 848 ℃, iqondo lokubila yi-1673 ℃. Kwi-1100 ~ 1200 degrees yaqala ukuguquguquka, umphunga u-alkaline. ILithium fluoride inyibilika kancinane emanzini kwaye ayinyibiliki etywaleni nakwezinye izinyibilikisi eziphilayo. Kwiqondo lobushushu begumbi, iLithium fluoride iyanyibilika kwi-nitric acid kunye ne-sulfuric acid, kodwa ayinyibiliki kwi-hydrochloric acid, kunye ne-hydrofluoric acid iLi2HF yetyuwa.
Sebenzisa Isetyenziswa njengezongezo ze-aluminium electrolysis kunye ne-electrolysis yomhlaba enqabileyo, ukwenziwa kweglasi ye-optical, i-desiccant, i-flux, njl.

Intshayelelo

Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-lithium fluoride:

 

Umgangatho:

1. ILithium fluoride yinto eqinileyo eyikristale emhlophe, ayinavumba kwaye ayinancasa.

3. I-soluble kancinane emanzini, kodwa i-soluble kwi-alcohols, i-acids kunye neziseko.

4. Yeyamakristale e-ionic, kunye nesakhiwo sayo sekristale yityhubhu egxile kumzimba.

 

Sebenzisa:

1. I-lithium fluoride isetyenziswa ngokubanzi njengokuguquguquka kweentsimbi ezifana ne-aluminiyam, i-magnesium, kunye nentsimbi.

2. Kwicandelo lenyukliya kunye ne-aerospace, i-lithium fluoride isetyenziswa njengesixhobo sokwenziwa kwamafutha e-reactor kunye neeblade ze-iturbine yeenjini ze-injini yomoya.

3. ILithium fluoride inobushushu obuphezulu bokunyibilika, kwaye ikwasetyenziswa njengokuguquguquka kweglasi kunye neeseramikhi.

4. Kwintsimi yeebhetri, i-lithium fluoride yinto ebalulekileyo ekrwada yokwenziwa kweebhetri ze-lithium-ion.

 

Indlela:

I-lithium fluoride idla ngokulungiswa ngezi ndlela zimbini zilandelayo:

1. Indlela ye-Hydrofluoric acid: i-hydrofluoric acid kunye ne-lithium hydroxide isabela ukuvelisa i-lithium fluoride kunye namanzi.

2. Indlela ye-Hydrogen fluoride: i-hydrogen fluoride idluliselwa kwisisombululo se-lithium hydroxide ukuvelisa i-lithium fluoride kunye namanzi.

 

Ulwazi ngoKhuseleko:

1. I-Lithium fluoride yinto edlayo enokucaphukisa ulusu kunye namehlo, kwaye kufuneka iphetshwe ngexesha lokusetyenziswa.

2. Xa uphethe i-lithium fluoride, iiglavu ezifanelekileyo zokukhusela kunye nezibuko kufuneka zinxitywe ukukhusela ukudibana ngengozi.

3. I-lithium fluoride kufuneka igcinwe kude nemithombo yokuvutha kunye nee-oxidants ukunqanda umlilo okanye ugqabhuko-dubulo.
