Dab tsi yog qhov txawv ntawm magnesium oxide thiab magnesium carbonate?

Magnesium oxidethiabmagnesium carbonatetxawv ntawm lawv cov khoom siv tshuaj.Magnesium carbonateyog ib qho tsis muaj zog acid uas yaj hauv dej thiab tawg mus rau hauv magnesium oxide thiab carbon dioxide thaum rhuab.Magnesium oxide, ntawm qhov tod tes, yog ib qho alkaline oxide uas yog insoluble hauv dej thiab tsis decompose thaum rhuab.

Daim ntawv thov kev lag luam thiab cov khoom yam ntxwv ntawm magnesium carbonate thiab magnesium oxide yog txawv raws li hauv qab no: Daim ntawv thov kev lag luam: Magnesium carbonate yog tsuas yog siv nyob rau hauv kws tshuaj intermediates, antacid, desiccant, colour tiv thaiv tus neeg saib xyuas, carrier, anti-coagulation agent thiab hais txog;Nyob rau hauv cov zaub mov raws li ib tug additive, magnesium element them nyiaj tus neeg saib xyuas;Hauv kev lag luam tshuaj zoo rau kev tsim cov tshuaj reagents;Siv los ua tus neeg saib xyuas thiab muab tub lim hauv roj hmab;Yuav siv tau raws li rwb thaiv tsev kub, kub resistant hluav taws rwb thaiv tsev ntaub ntawv;Hlau thiab cable raug txheej txheem tseem ceeb tshuaj raw cov ntaub ntawv, thiab lwm yam Magnesium oxide yog tsuas yog siv nyob rau hauv silicon steel, catalyst, kws kev lag luam, zaub mov kev lag luam, cosmetic raw khoom, yas additives, roj hmab additives, electrode cov ntaub ntawv, iav substrate cov ntaub ntawv thiab lwm yam teb.Khoom nta: Magnesium carbonate yog cov xim tsis muaj pob tshab, alkaline, soluble hauv dej, me ntsis alkaline;Magnesium oxide, ntawm qhov tod tes, yog cov hmoov dawb, alkaline thiab insoluble hauv dej.

Magnesium carbonate yog cais raws li hauv qab no:

Lub teeb magnesium carbonate: dawb nkig los yog xoob dawb hmoov, tsw ntxhiab, ruaj khov hauv huab cua.Thaum rhuab mus rau 700 ° C, nws decomposes tsim magnesium oxide, carbon dioxide thiab dej.Nyob rau hauv chav tsev kub, nws yog ib tug trihydrate ntsev.Hnyav magnesium carbonate: hmoov dawb, tasteless, insoluble hauv dej, rhuab mus rau ntau tshaj 150 ℃ decomposition, tsim magnesium oxide thiab carbon dioxide.Nyob rau hauv chav tsev kub, nws yog hexahydrate ntsev.

Kev faib tawm ntawm magnesium oxide yog raws li nram no:

Lub teeb magnesium oxide: cov mis mos molecular yog MgO, cov tsos yog dawb los yog beige lub teeb hmoov, tsw thiab saj tsis qab.Los ntawm huab cua, nws yooj yim nqus dej thiab carbon dioxide, insoluble hauv dej thiab cawv, thiab soluble hauv dilute acids.Active magnesium oxide: daim ntawv thov qeeb, siv rau neoprene roj hmab filling, txhawb zog thiab ua ib qho catalyst.Hnyav magnesium oxide: Molecular mis MgO, zoo li cov hmoov dawb, tsis muaj ntxhiab, insoluble hauv dej.Thaum rhuab mus rau ntau tshaj 1500 ℃, nws yuav tuag hlawv magnesium oxide (magnesia) los yog sintered magnesium oxide.
