Na Waiwai Kino a Kimia Lithium fluoride ka pauka keʻokeʻo, sodium chloride type crystal structure. ʻO ka mānoanoa pili 2.640, kahi heheʻe 848 ℃, kahi paila 1673 ℃. Ma 1100 ~ 1200 degere hoʻomaka e volatilize, ka mahu mea alkaline. Hiki ke hoʻoheheʻe ʻia ka Lithium fluoride i ka wai a hiki ʻole ke hoʻoheheʻe ʻia i ka waiʻona a me nā mea hoʻoheheʻe organik. Ma ka lumi wela, hiki ke hoʻoheheʻe ʻia ka Lithium fluoride i loko o ka waikawa nitric a me ka sulfuric acid, akā hiki ʻole ke hoʻoheheʻe ʻia i loko o ka waika hydrochloric, me ka hydrofluoric acid Li2HF acid paʻakai.
Hoʻohana Hoʻohana ʻia e like me nā mea hoʻohui no ka electrolysis alumini a me ka electrolysis honua ʻole, ka hana aniani optical, desiccant, flux, etc.

Hoʻolauna

ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka lithium fluoride:

 

ʻAno maikaʻi:

1. Lithium fluoride he keʻokeʻo crystalline paa, odorless a me ka ono.

3. Hiki ke hoʻoheheʻe ʻia i loko o ka wai, akā hiki ke hoʻoheheʻe ʻia i loko o ka waiʻona, nā waikawa a me nā kumu.

4. Aia ia i nā kristal ionic, a ʻo kona ʻano aniani he cube i waena o ke kino.

 

E hoʻohana:

1. Hoʻohana nui ʻia ka Lithium fluoride e like me ka flux no nā metala e like me ka aluminika, ka magnesium, a me ka hao.

2. Ma nā ʻāpana nuklea a me ka aerospace, hoʻohana ʻia ka lithium fluoride ma ke ʻano he mea hana no ka hana ʻana i ka wahie reactor a me nā lau turbine no nā mīkini turbine.

3. He kiʻekiʻe ka wela hoʻoheheʻe ʻana o Lithium fluoride, a hoʻohana ʻia hoʻi e like me ka flux i ke aniani a me nā seramika.

4. Ma ke kahua o nā pila, lithium fluoride he mea waiwai nui no ka hana ʻana i nā pā lithium-ion.

 

Hanana:

Hoʻomākaukau pinepine ʻia ka Lithium fluoride e nā ʻano ʻelua:

1. Hydrofluoric acid ala: hydrofluoric acid a me lithium hydroxide e hoʻoulu ai i ka lithium fluoride a me ka wai.

2. ʻO ke ʻano o ka hydrogen fluoride: hāʻawi ʻia ka hydrogen fluoride i loko o ka solution lithium hydroxide e hana ai i ka fluoride lithium a me ka wai.

 

ʻIke palekana:

1. ʻO Lithium fluoride kahi mea ʻino i loaʻa ka hopena hoʻonāukiuki i ka ʻili a me nā maka, a pono e pale ʻia i ka wā hoʻohana.

2. I ka lawelawe ʻana i ka lithium fluoride, pono e hoʻohana ʻia nā mīkina lima pale kūpono a me nā maka aniani e pale ai i ka hoʻopili ʻana.

3. Pono e hoʻokaʻawale ʻia ka lithium fluoride mai nā kumu hoʻāla a me nā mea oxidants e pale aku i ke ahi a pahū paha.
