I-Synthetic Cryolite yokuCasa |15096-52-3

I-Cryolite isetyenziselwa ukuphosa okwangoku.I-Cryolite iphinda isetyenziswe ngokukodwa kwimveliso ye-ductile iron.Imiyalelo ephambili yile ilandelayo:

1. Phalaza phezu kobuso bentsimbi etyhidiweyo, inani li-0.1% -0.3%, kwaye indima yalo kukususa i-slag kunye nokugubungela konke.

I-Cryolite inokunciphisa i-slag ukuze iqokelelwe kwaye isuswe.

I-Cryolite iyabola xa ishushu (ngaphezu kwe-1011℃) ukuze ivelise i-aluminium fluoride (AlF3) igesi, enokukhusela umphezulu wentsimbi etyhidiweyo kwaye ithintele i-oxidation, kodwa le gesi iyingozi kumzimba womntu.

2. Umphezulu womgodi omanzi uhlanganiswe ne-cryolite powder, ekhusela ngokufanelekileyo ukuvela kwe-pores subcutaneous.

Emva kokugalelwa, kukho i-cryolite inyibilika umaleko kwi-metal-mold interface, enokuthi inyibilikise impendulo yokunciphisa umphunga wamanzi kwi-interface, enciphisa isiseko esifunekayo kwi-hydrogen kwi-interface etyhidiweyo umaleko wentsimbi ukwenza i-bubble core;

Irhasi ye-aluminiyam ye-fluoride eveliswe kukubola kwe-cryolite esezantsi inokukhusela umaleko we-ferroelectric ohlangeneyo ukusuka kwiindlela ezahlukeneyo zeekhemikhali kumaleko wobuso, ukuthintela umaleko we-ferromagnetic ohlangeneyo ekufunxeni i-hydrogen.

Iimpawu ezibonakalayo ze-Cryolite: i-sodium hexafluoroaluminate, i-molecular formula Na3AlF6, ubunzima be-molecular yi-209.94, iyinto eyinkimbinkimbi, akunakwenzeka ukuba ibe yityuwa kabini, i-Na + ion kunye ne- [AlF6] i-3-ion ikhona emva kokuchithwa.

I-Non-toxic, imhlophe, imhlophe, i-powder emthubi okanye i-crystalline amasuntswana ngenxa yokungcola, indawo yokunyibilika kwayo yi-1025 ℃, ubuninzi be-0.6 ~ 1.0g / L, ubuninzi bokwenene yi-2.95 ~ 3.05g / cm3, isizukulwana sobushushu yi-225KJ ,

Ubunzima obuthile yi-2.75 ~ 3.00g / cm3, ukushisa kwe-fusion yi-107KJ, iikristale ze-monoclinic ezingenambala, imbonakalo iphantse ibe yi-cubic, kwaye imveliso ecocekileyo ayinambala.Idla ngokuba mhlophe-mhlophe, tyheli elikhanyayo, bubomvu okhanyayo, kwaye imnyama ngenxa yobumdaka.

Idla ngokuba yibhloko eshinyeneyo engafanelekanga ukwahlulahlula.Ukubengezela kwayo kuyabonakala kwaye kufumile, imigca yayo imhlophe, yaye inokukhanya kweglasi.

Ukufunxa ngokulula amanzi kunye nokufuma, ukunyibilika kancinane emanzini, isisombululo samanzi sineasidi, kwaye sikhupha igesi eyityhefu ye-HF xa idibana ne-asidi yesulfuric.

Ngokuqhelekileyo isetyenziswa njenge-flux ye-aluminium yokunyibilika, izitshabalalisi zezityalo, njenge-flux ye-ceramic glazes, kunye ne-arhente ye-opalescent;ikwasetyenziselwa ukuvelisa iglasi opalescent, kwaye ingasetyenziswa njenge electrolyte ukuveliswa ingxubevange aluminiyam, ingxubevange yentsimbi, kunye neentsimbi abilayo, kunye namavili lokusila, Izithako njl.

Iphakheji: 25KG / BAG okanye njengoko ucela.

Ugcino: Gcina kwindawo engenamoya, eyomileyo.

Umgangatho wesiGqeba: uMgangatho waMazwe ngaMazwe.
