Zakuthupi ndi Zamankhwala Lithium fluoride ndi ufa woyera, mtundu wa kristalo wa sodium chloride. Kachulukidwe wachibale 2.640, malo osungunuka 848 ℃, mfundo yowira 1673 ℃. Pa 1100 ~ 1200 madigiri anayamba volatilize, nthunzi ndi zamchere. Lithium fluoride amasungunuka pang'ono m'madzi ndipo samasungunuka mu mowa ndi zosungunulira zina. Kutentha, Lithium fluoride imasungunuka mu nitric acid ndi sulfuric acid, koma osasungunuka mu hydrochloric acid, ndi hydrofluoric acid Li2HF acid mapangidwe amchere.
Gwiritsani ntchito Amagwiritsidwa ntchito ngati zowonjezera za aluminiyamu electrolysis ndi osowa lapansi electrolysis, kuwala galasi kupanga, desiccant, flux, etc.

Mawu Oyamba

Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha lithiamu fluoride:

 

Ubwino:

1. Lithium fluoride ndi woyera mwala wolimba, wopanda fungo komanso wosakoma.

3. Kusungunuka pang'ono m'madzi, koma kusungunuka mu ma alcohols, ma acid ndi maziko.

4. Ndi ya makristasi a ionic, ndipo mawonekedwe ake a kristalo ndi cube yokhazikika pathupi.

 

Gwiritsani ntchito:

1. Lithium fluoride imagwiritsidwa ntchito kwambiri ngati chitsulo chosungunula zitsulo monga aluminiyamu, magnesium, ndi chitsulo.

2. M'magawo a nyukiliya ndi zamlengalenga, lithiamu fluoride imagwiritsidwa ntchito ngati zinthu zopangira mafuta opangira mafuta ndi masamba a turbine pama injini a turbine.

3. Lithiamu fluoride imakhala ndi kutentha kwakukulu kosungunuka, ndipo imagwiritsidwanso ntchito ngati kusinthasintha kwa galasi ndi zoumba.

4. M'munda wa mabatire, lithiamu fluoride ndizofunikira kwambiri popanga mabatire a lithiamu-ion.

 

Njira:

Lithium fluoride nthawi zambiri imakonzedwa ndi njira ziwiri izi:

1. Njira ya Hydrofluoric acid: hydrofluoric acid ndi lithiamu hydroxide amachitidwa kuti apange lithiamu fluoride ndi madzi.

2. Njira ya haidrojeni fluoride: hydrogen fluoride imadutsa mu lithiamu hydroxide solution kuti ipange lithiamu fluoride ndi madzi.

 

Zambiri Zachitetezo:

1. Lithium fluoride ndi zinthu zowononga zomwe zimawononga khungu ndi maso, ndipo ziyenera kupewedwa mukamagwiritsa ntchito.

2. Pogwira ntchito ya lithiamu fluoride, magolovesi oteteza ndi magalasi oyenera ayenera kuvala kuti asakhudzidwe mwangozi.

3. Lithiamu fluoride iyenera kusungidwa kutali ndi poyatsira ndi ma oxygen kuti pasakhale moto kapena kuphulika.
