Tilmaamaha Jirka iyo Kiimikada Lithium fluoride waa budo cad, qaab-dhismeedka kristal sodium chloride. Cufnaanta qaraabada 2.640, barta dhalaalka 848 ℃, barta karkarinta 1673 ℃. Markay tahay 1100 ~ 1200 digrii ayaa bilaabay inay isbedesho, uumiga waa alkaline. Lithium fluoride wax yar bay ku milmi kartaa biyaha oo aan lagu milmi karin khamriga iyo dareerayaasha kale ee organic. Heerkulka qolka, lithium fluoride wuxuu ku milmaa nitric acid iyo sulfuric acid, laakiin kuma milmi karo asiidhka hydrochloric, oo leh hydrofluoric acid Li2HF acid cusbada.
Isticmaal Waxa loo isticmaalaa sida wax lagu daro aluminium electrolysis iyo electrolysis dhulka naadir ah, wax soo saarka muraayadaha indhaha, qalajiyaha, qulqulka, iwm

Hordhac

Kuwa soo socdaa waa horudhac ku saabsan sifooyinka, isticmaalka, hababka diyaarinta iyo macluumaadka badbaadada lithium fluoride:

 

Tayada:

1. Lithium fluoride waa crystalline cad oo adag, aan ur lahayn oo aan dhadhamin.

3. Waxoogaa ku milmay biyaha, laakiin waxay ku milmaan alkolada, asiidhka iyo saldhigyada.

4. Waxay ka tirsan tahay kiristaalo ionic, iyo qaab dhismeedkeedu waa cube jidhka ku salaysan.

 

Isticmaal:

1. Lithium fluoride waxaa si weyn loogu isticmaalaa qulqulka biraha sida aluminium, magnesium, iyo birta.

2. Qaybaha nukliyeerka iyo hawada hawada, lithium fluoride waxa loo isticmaalaa sidii wax lagu soo saaro shidaalka reactor iyo marawaxadaha marawaxadaha ee matoorada marawaxadaha.

3. Lithium fluoride waxa uu leeyahay heerkul dhalaal oo sarreeya, waxa kale oo loo isticmaalaa sida qulqulka galaaska iyo ceramics.

4. Dhinaca baytariyada, lithium fluoride waa shay ceeriin ah oo muhiim u ah soo saarista baytariyada lithium-ion.

 

Habka:

Lithium fluoride waxaa badanaa lagu diyaariyaa labada hab ee soo socda:

1. Habka Hydrofluoric acid: hydrofluoric acid iyo lithium hydroxide ayaa laga falceliyaa si ay u dhaliyaan lithium fluoride iyo biyo.

2. Habka fluoride hydrogen: hydrogen fluoride waxa loo gudbiyaa xal lithium hydroxide si loo dhaliyo lithium fluoride iyo biyo.

 

Macluumaadka Badbaadada:

1. Lithium fluoride waa walax daxalaysa maqaarka iyo indhaha, waana in laga fogaadaa marka la isticmaalayo.

2. Markaad la tacaalayso lithium fluoride, galoofyada ilaalinta ku habboon waa in la xidho si looga hortago taabasho shil ah.

3. Lithium fluoride waa in laga fogeeyaa ilaha shidda iyo oxidants si looga fogaado dab ama qarax.
