Āhuatanga ā-tinana, matū hoki Lithium fluoride he paura ma, konutai pūhaumāota momo hanganga tioata. Kiato pātahi 2.640, ira whakarewa 848 ℃, ira kohua 1673 ℃. I te 1100 ~ 1200 nga nekehanga ka timata ki te whakaheke, he kawakore te kohu. He paku te wairewa Lithium fluoride ki te wai, karekau ki te waipiro me etahi atu whakarewa pararopi. I te pāmahana rūma, ka whakarewahia te Lithium fluoride i roto i te waikawa nitric me te waikawa pungatara, engari karekau i te waikawa waikawa, me te waikawa waikawa Li2HF te hanga tote waikawa waikawa.
Whakamahi Ka whakamahia hei taapiri mo te electrolysis konumohe me te electrolysis whenua onge, hanga karaihe whatu, desiccant, flux, etc

Kupu Whakataki

E whai ake nei he kupu whakataki mo nga rawa, nga whakamahinga, nga tikanga whakarite me nga korero haumaru o te lithium fluoride:

 

Kounga:

1. Ko te Lithium fluoride he kirikiriata ma, he hongi me te kore reka.

3. He iti te wairewa ki te wai, engari ka whakarewahia ki te waipiro, te waikawa me te kawakore.

4. No nga tioata katote, a ko tona hanganga karaihe he poraka-a-tinana.

 

Whakamahia:

1. Ka whakamahia nuitia te Lithium fluoride hei rerenga mo nga konganuku penei i te konumohe, te konupora, me te rino.

2. I roto i nga waahanga karihi me te aerospace, ka whakamahia te lithium fluoride hei taonga mo te hanga wahie reactor me nga mata hiko mo nga miihini hiko.

3. Lithium fluoride he teitei te wera o te rewa, a ka whakamahia ano he rere i roto i te karaihe me nga karaera.

4. I roto i te waahi o nga papahiko, ko te lithium fluoride he mea tino nui mo te hanga i nga papahiko lithium-ion.

 

Tikanga:

Ko te Lithium fluoride i te nuinga o te waa ka rite ma nga tikanga e rua e whai ake nei:

1. Tikanga waikawa waiwaro: ka tauhohehia te waikawa waiwaro me te lithium hydroxide ki te whakaputa lithium fluoride me te wai.

2. Tikanga pūkōwhai hauwai: ka tukuna te pūkōwhai hauwai ki te wairewa lithium hydroxide hei whakaputa lithium fluoride me te wai.

 

Mōhiohio Haumaru:

1. Ko te Lithium fluoride he matū pirau e pa ana ki te kiri me nga kanohi, me karo i te wa e whakamahia ana.

2. I te wa e whakahaere ana koe i te lithium fluoride, me mau nga karapu whakamarumaru me nga karaehe kia kore e pa mai.

3. Me noho matara atu te pukoro Lithium mai i nga puna mura me nga waiora kia kore ai te ahi, te pahūtanga ranei.
