Gabatarwa

Mai zuwa shine gabatarwa ga kaddarorin, amfani, hanyoyin shiri da bayanan aminci na lithium fluoride:

 

inganci:

1. Lithium fluoride fari ne mai kauri, mara wari kuma marar ɗanɗano.

3. Dan kadan mai narkewa a cikin ruwa, amma mai narkewa a cikin alcohols, acids da tushe.

4. Nasa ne na lu'ulu'u na ionic, kuma tsarinsa na crystal cube ne na tsakiya.

 

Amfani:

1. Lithium fluoride ana amfani dashi sosai azaman juzu'i don karafa kamar aluminum, magnesium, da baƙin ƙarfe.

2. A cikin sassan nukiliya da sararin samaniya, ana amfani da lithium fluoride a matsayin wani abu don kera man fetur da injin turbine don injunan turbine.

3. Lithium fluoride yana da yawan zafin jiki na narkewa, kuma ana amfani dashi azaman juzu'i a cikin gilashi da yumbu.

4. A fagen batura, lithium fluoride wani muhimmin kayan da ake buƙata don kera batirin lithium-ion.

 

Hanya:

Lithium fluoride yawanci ana shirya shi ta hanyoyi biyu masu zuwa:

1. Hydrofluoric acid Hanyar: hydrofluoric acid da lithium hydroxide suna amsa don samar da lithium fluoride da ruwa.

2. Hanyar fluoride na hydrogen: hydrogen fluoride yana shiga cikin maganin lithium hydroxide don samar da lithium fluoride da ruwa.

 

Bayanin Tsaro:

1. Lithium fluoride wani abu ne mai lalata wanda ke da illa ga fata da idanu, kuma yakamata a kiyaye shi yayin amfani da shi.

2. Lokacin sarrafa lithium fluoride, ya kamata a sa safar hannu da tabarau masu kariya da suka dace don hana haɗuwa da haɗari.

3. Lithium fluoride ya kamata a nisanta daga tushen kunnawa da kuma abubuwan da ke haifar da iskar oxygen don guje wa wuta ko fashewa.
