Cryolite sịntetik maka nkedo | 15096-52-3

A na-eji cryolite eme ihe nkedo ugbu a. A na-ejikwa cryolite eme ihe karịsịa na mmepụta nke ígwè ductile. Isi ntuziaka bụ ndị a:

1. Wụsa n'elu ígwè a wụrụ awụ, ego ahụ bụ 0.1% -0.3%, ọrụ ya bụ iwepụ slag ma kpuchie ihe niile.

Cryolite nwere ike imebi slag ka e wee nwee ike ịnakọta ya ma wepụ ya.

Cryolite decomposes mgbe kpụ ọkụ n'ọnụ (karịa 1011 ℃) na-emepụta aluminum fluoride (AlF3) gas, nke nwere ike ichekwa n'elu nke a wụrụ awụ ígwè ma gbochie oxidation, ma gas a na-emerụ ahụ mmadụ.

2. A na-ekpuchi elu nke oghere mmiri mmiri na cryolite ntụ ntụ, nke na-egbochi nke ọma ihe omume nke pores subcutaneous.

Mgbe wụsara, e nwere cryolite gbazee oyi akwa na metal-ebu interface, nke nwere ike igbari mmiri vepo Mbelata mmeghachi omume na interface, nke na-ebelata isi chọrọ hydrogen evolushọn na interface gbazere ígwè oyi akwa na-etolite afụ isi;

Aluminom fluoride gas nke a na-emepụta site na nbibi nke obere cryolite nwere ike ichebe oyi akwa ferroelectric interfacial site na mmeghachi omume kemịkal dị iche iche na oyi akwa interfacial, na-egbochi oghere ferromagnetic interfacial site na ịmịnye hydrogen.

Njirimara anụ ahụ nke Cryolite: sodium hexafluoroaluminate, usoro molecular Na3AlF6, ịdị arọ molecular bụ 209.94, bụ nke mgbagwoju anya, ọ gaghị ekwe omume ịbụ nnu abụọ, Na + ion na [AlF6] 3- ion dị mgbe ọ gbasasịrị.

Na-adịghị egbu egbu, na-acha ọcha, na-acha ọcha, odo ntụ ntụ ma ọ bụ crystalline ahụ n'ihi adịghị ọcha, ya na-agbaze ebe bụ 1025 ℃, nnukwu njupụta bụ 0.6 ~ 1.0g / L, ezi njupụta bụ 2.95 ~ 3.05g / cm3, okpomọkụ ọgbọ bụ 225KJ. ,

Nnukwu ike ndọda bụ 2.75 ~ 3.00g / cm3, okpomọkụ nke ngwakọta bụ 107KJ, kristal monoclinic na-enweghị agba, ọdịdị ya fọrọ nke nta ka ọ bụrụ cubic, na ngwaahịa dị ọcha enweghị agba. Ọ na-adịkarị ọcha, na-acha odo odo, na-acha uhie uhie, na oji n'ihi adịghị ọcha.

Ọ na-abụkarị nnukwu ngọngọ nke na-adabaghị maka nkewa. Ihe na-egbuke egbuke ya na-apụta ìhè na mmiri, n'ọnyá ya na-acha ọcha, ma nwee ihe na-egbuke egbuke.

Na-amịkọrọ mmiri na mmiri ngwa ngwa, na-agbaze ntakịrị na mmiri, ngwọta mmiri bụ acidic, ọ na-ahapụkwa HF gas na-egbu egbu mgbe ọ zutere sulfuric acid.

A na-ejikarị ya eme ihe maka ịgbaze aluminom, ọgwụ pesticides maka ihe ọkụkụ, dị ka mmiri maka seramiiki glazes, na dị ka onye na-ahụ maka opalescent; a na-ejikwa ya na-emepụta iko opalescent, a pụkwara iji ya mee ihe dị ka electrolyte maka mmepụta nke aluminom alloys, ígwè alloys, na nchara na-esi ísì ụtọ, na maka ịkwanye wiil, Efrata wdg.

Ngwugwu: 25KG / BAG ma ọ bụ dị ka ịchọrọ.
