Atẹle jẹ ifihan si awọn ohun-ini, awọn lilo, awọn ọna igbaradi ati alaye ailewu ti lithium fluoride:

 

Didara:

1. Litiumu fluoride jẹ kirisita funfun ti o lagbara, olfato ati ailẹgbẹ.

3. Die-die tiotuka ninu omi, ṣugbọn tiotuka ninu awọn ọti-lile, acids ati awọn ipilẹ.

4. O je ti awọn kirisita ionic, ati awọn oniwe-gara be ni ara-ti dojukọ cube.

 

Lo:

1. Lithium fluoride jẹ lilo pupọ bi ṣiṣan fun awọn irin bii aluminiomu, iṣuu magnẹsia, ati irin.

2. Ni awọn apa iparun ati awọn aerospace, litiumu fluoride ti wa ni lo bi awọn kan ohun elo fun awọn ẹrọ ti reactor idana ati turbine abe fun turbine enjini.

3. Lithium fluoride ni iwọn otutu ti o ga, ati pe o tun lo bi ṣiṣan ni gilasi ati awọn ohun elo amọ.

4. Ni aaye ti awọn batiri, lithium fluoride jẹ ohun elo aise pataki fun iṣelọpọ awọn batiri lithium-ion.

 

Ọna:

Lithium fluoride jẹ igbagbogbo pese sile nipasẹ awọn ọna meji wọnyi:

1. Hydrofluoric acid ọna: hydrofluoric acid ati lithium hydroxide ti wa ni reacted lati se ina litiumu fluoride ati omi.

2. Hydrogen fluoride ọna: hydrogen fluoride ti wa ni koja sinu lithium hydroxide ojutu lati se ina lithium fluoride ati omi.

 

Alaye Abo:

1. Lithium fluoride jẹ nkan ti o bajẹ ti o ni ipa irritating lori awọ ara ati oju, ati pe o yẹ ki o yee nigba lilo.

2. Nigbati o ba n mu litiumu fluoride mu, awọn ibọwọ aabo ti o yẹ ati awọn goggles yẹ ki o wọ lati ṣe idiwọ olubasọrọ lairotẹlẹ.
