Okwu mmalite

Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke lithium fluoride:

 

Ogo:

1. Lithium fluoride bụ kristal ọcha siri ike, enweghị isi na enweghị ụtọ.

3. Nri dị ntakịrị na mmiri, ma soluble na alcohols, acids na bases.

4. Ọ bụ nke kristal ionic, na kristal Ọdịdị ya bụ cube nke dabere na ahụ.

 

Jiri:

1. A na-eji lithium fluoride eme ihe n'ọtụtụ ebe dị ka ntụgharị maka ọla dị ka aluminom, magnesium, na ígwè.

2. Na mpaghara nuklia na nke ikuku, a na-eji lithium fluoride mee ihe maka imepụta mmanụ ọkụ na turbine maka injin turbine.

3. Lithium fluoride nwere okpomọkụ na-agbaze dị elu, a na-ejikwa ya dị ka ntụgharị na iko na seramiki.

4. N'ihe gbasara batrị, lithium fluoride bụ ihe dị mkpa maka ịmepụta batrị lithium-ion.

 

Usoro:

A na-akwadokarị lithium fluoride site na ụzọ abụọ ndị a:

1. Usoro hydrofluoric acid: hydrofluoric acid na lithium hydroxide na-emeghachi omume iji mepụta lithium fluoride na mmiri.

2. Usoro hydrogen fluoride: hydrogen fluoride na-agafe na lithium hydroxide ngwọta iji mepụta lithium fluoride na mmiri.

 

Ozi nchekwa:

1. Lithium fluoride bụ ihe na-emebi emebi nke nwere mmetụta na-akpasu iwe na akpụkpọ ahụ na anya, na ekwesịrị izere ya mgbe ejiri ya.

2. Mgbe ị na-ejikwa lithium fluoride, gloves nchebe kwesịrị ekwesị kwesịrị iyiri iji gbochie kọntaktị mberede.

3. Lithium fluoride kwesịrị ka ewepụ ya na isi mmalite ọkụ na oxidants iji zere ọkụ ma ọ bụ mgbawa.
