Izakhiwo Zomzimba Nezamakhemikhali I-Lithium fluoride iyimpuphu emhlophe, isakhiwo sekristalu sohlobo lwe-sodium chloride. Ukuminyana okuhlobene 2.640, iphoyinti elincibilikayo 848 ℃, indawo yokubilisa 1673 ℃. Ku-1100 ~ 1200 degrees waqala ukuguquguquka, umhwamuko une-alkaline. I-Lithium fluoride inyibilika kancane emanzini futhi ayincibiliki otshwaleni nakwezinye izincibilikisi eziphilayo. Ezingeni lokushisa legumbi, i-Lithium fluoride iyancibilika ku-nitric acid ne-sulfuric acid, kodwa ayincibiliki ku-hydrochloric acid, nge-hydrofluoric acid Li2HF acid kwakheka usawoti.
Sebenzisa Isetshenziswa njengezithasiselo ze-aluminium electrolysis kanye ne-electrolysis yomhlaba engavamile, ukukhiqizwa kwengilazi ebonakalayo, i-desiccant, i-flux, njll.

Isingeniso

Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-lithium fluoride:

 

Ikhwalithi:

1. I-Lithium fluoride iyikristale eqinile emhlophe, ayinaphunga futhi ayinambitheki.

3. Incibilika kancane emanzini, kodwa incibilika kuma-alcohol, ama-asidi nezisekelo.

4. Iyingxenye yamakristalu e-ionic, futhi ukwakheka kwayo kwekristalu kuyi-cube egxile emzimbeni.

 

Sebenzisa:

1. I-Lithium fluoride isetshenziswa kakhulu njengendlela yokuguquguquka kwezinsimbi ezifana ne-aluminium, i-magnesium, nensimbi.

2. Emkhakheni we-nuclear kanye ne-aerospace, i-lithium fluoride isetshenziswa njengento yokwenza uphethiloli we-reactor nama-turbine blades ezinjini ze-turbine.

3. I-lithium fluoride inezinga lokushisa eliphakeme lokuncibilika, futhi isetshenziswa futhi njengokuguquguquka engilazini nasezitsheni zobumba.

4. Emkhakheni wamabhethri, i-lithium fluoride iyimpahla ebalulekile yokukhiqiza amabhethri e-lithium-ion.

 

Indlela:

I-Lithium fluoride ivamise ukulungiswa ngezindlela ezimbili ezilandelayo:

1. Indlela ye-Hydrofluoric acid: I-hydrofluoric acid ne-lithium hydroxide ziyasabela ukuze kukhiqizwe i-lithium fluoride namanzi.

2. Indlela ye-Hydrogen fluoride: I-hydrogen fluoride idluliselwa kusisombululo se-lithium hydroxide ukuze ikhiqize i-lithium fluoride namanzi.

 

Ulwazi Lokuphepha:

1. I-Lithium fluoride iyinto edlayo enomphumela ocasulayo esikhumbeni nasemehlweni, futhi kufanele igwenywe lapho isetshenziswa.

2. Lapho uphatha i-lithium fluoride, amagilavu ​​okuvikela afanelekile kanye nezibuko kufanele kugqokwe ukuze kuvinjelwe ukuthintana ngengozi.

3. I-lithium fluoride kufanele igcinwe kude nemithombo yokuthungela kanye nama-oxidants ukugwema umlilo noma ukuqhuma.
