| Cryolite Siv Thiab Synthesis |
| Kev piav qhia | Cryolite yog ib qho tsis tshua muaj ntxhia ntsev ntawm sodium, fluoride thiab txhuas uas tau pom thawj zaug ntawm ntug dej hiav txwv sab hnub poob ntawm Greenland. Cov khoom siv tau ploj mus los ntawm xyoo 1987, thiab cov khoom siv hluavtaws tam sim no yog tsim los ntawm cov ntxhia pob zeb fluorite. Cryolite yog siv rau ntawm daim ntawv thov siab heev ntawm 5-30 kg/ha los tswj Lepidoptera thiab Coleoptera ntawm qee cov txiv hmab txiv ntoo, zaub thiab citrus. 92% ntawm tag nrho cov cryolite siv hauv Teb Chaws Asmeskas yog siv rau txiv hmab hauv California. |
| Chemical Properties | Sodium aluminium fluoride yog cov daus-dawb crystalline khoom, hmoov los yog vitreous loj. Cov khoom siv crystalline (natural khoom (cryolite) tej zaum yuav muaj xim liab los yog xim av los yog txawm dub tab sis poob no discoloration ntawm cua sov); Cov khoom siv hluavtaws yog cov hmoov amorphous. Tsis hnov tsw |
| Lub cev muaj zog | Cwj pwm: loj, granular, pseudocubic euhedral crystals. Xim: daus dawb, grey, liab dawb, lossis xim av dawb. Diaphaneity: pob tshab rau translucent. Luster: vitreous, greasy. Streak: dawb. Cleavage: [001], [110], [101]. Kev tawg: tsis sib xws. Qhov tshwm sim: lub txaj loj nyob rau hauv cov hlab ntsha ntawm cov hlab ntsha hauv grey gneiss. Melting point: 1009 degree. |
| Siv | Electrolyte hauv kev txo qis ntawm alumina rau txhuas; ceramics; tshuaj tua kab; binder rau abrasives; hluav taws xob rwb thaiv tsev; cov khoom tawg; polishes. |
| Siv | Cryolite feem ntau yog siv los ua ib qho electrolyte rau txhuas electrolysis. Alumina yaj nyob rau hauv molten cryolite yog siv los yaj alumina thaum lub sij hawm ua txhuas. |
| Txhais | Lub ntuj fluoride ntawm sodium thiab txhuas los yog tsim los ntawm fluorspar, sulfuric acid, hydrated alumina, thiab sodium carbonate. |
| Kev piav qhia dav dav | Ib qho tsis muaj ntxhiab tsw dawb los yog hmoov. Mp: 1291 degree. Qhov ceev: 2.95 g cm -3. Plua plav ua rau lub qhov muag thiab tawv nqaij; nqus plua plav ua rau lub qhov ntswg, qhov ncauj thiab lub ntsws. Insoluble hauv dej. Synthesized los ntawm fusion ntawm sodium fluoride thiab txhuas fluoride raws li ib tug electrolyte nyob rau hauv txo cov alumina rau txhuas hlau. Nws tshwm sim nyob rau hauv qhov zoo li cov ntxhia cryolite. Aqueous suspensions ntawm hmoov sodium aluminium fluoride yog siv los ua tshuaj tua kab. |
| Reactivity Profile | SODIUM ALUMINIUM FLUORIDE yog tsis-combustible. Emits toxic fumes thaum rhuab mus decomposition. Incompatible nrog muaj zog oxidizing neeg sawv cev thiab muaj zog acids. Decomposed los ntawm cov hauv paus, uas tuaj yeem tsim cov fluorides soluble. Soluble nyob rau hauv concentrated sulfuric acid. |
| Kev Siv Agricultural | Insecticide: Sodium aluminium fluoride yog siv los ua tshuaj tua kab ntawm cov qoob loo thiab cov khoom siv kho kom zoo nkauj, thiab tseem siv rau hauv aluminium refining thiab ua ceramics, iav thiab polishes. Cryolite yog siv los tswj ntau yam kab tsuag ntawm cucurbits (melons, cantaloupe, watermelon, taub dag, txhua hom squash), txiv hmab txiv ntoo zaub (eggplant, kua txob, zaub paj, Brussels sprouts, zaub qhwv, zaub qhwv, paj noob hlis, taub hau thiab nplooj lettuce, kohlrabi), kiwi (hauv California nkaus xwb), pears, radish, cranberry thiab txiv duaj, txiv kab ntxwv, txiv qaub, txiv qaub, txiv kab ntxwv, tangelo, tangerines, txiv lws suav, txiv apples, qos yaj ywm, taum thiab txiv hmab txiv ntoo. Tsis tas li ntawd nyob rau hauv ornamental nroj tsuag, woody shrubs thiab vines. Tsis muaj npe rau siv hauv EU lub teb chaws. Sau npe siv hauv Teb Chaws Asmeskas |
