Kutheni i-magnesium oxide enganyangekiyo kumaqondo aphezulu obushushu? Ngobushushu obunjani i-magnesium oxide inokufezekisa ukuntywila? Buyintoni ubushushu bokuntywila kwimagnesium oxide?

I-Magnesium oxide yaziwa ngokuba ngumhlaba okrakra, okanye i-magnesia, enendawo yokunyibilika ye-2852 ° C, indawo yokubilisa ye-3600 ° C, kunye nobuninzi be-3.58 (25 ° C). Isinyibilikisi isisombululo seasidi kunye neammonium, inyibilika ngotywala. I-Magnesium oxide inesidanga esiphezulu sepropathi ekhusayo kunye nepropathi. Inokuguqulwa ibe ziikristale emva kokutshiswa kubushushu obuphezulu ngaphezulu kwe-1000 ° C. Xa inyuka iye kwi-1500-2000 ° C, iba yimagnesia etshisiweyo efileyo (ekwabizwa ngokuba yimagnesia) okanye i-magnesia esintini.

Intshayelelo yeMagnesium oxide:

I-Magnesium oxide (ifomula yamachiza: MgO) yi-magnesium oxide, i-ionic compound. Yinto emhlophe eqinileyo kubushushu begumbi. Magnesium oxide ikhona kwindalo ngohlobo lwe-periclase kwaye yinto ekrwada yokunyibilikisa i-magnesium.

Magnesium oxide inokumelana nomlilo kunye neepropathi zokugquma. Emva kokutshiswa kubushushu obuphezulu ngaphezulu kwe-1000 ° C, inokuguqulwa ibe ziikristale. Xa inyuka yaya kwi-1500-2000 ° C, iya kuba yimagnesia etshisiweyo (ekwabizwa ngokuba yi-magnesia) okanye i-sintered magnesia.

Magnesium oxide ngesiNgesi yiMagnesium oxide okanye iMagnesium monooxid

Zithini ii-magnesium oxides?

I-Magnesium oxide yahlulwe yaziindidi ezimbini: ukukhanya kwemagnesia kunye nemagnesia enzima.

Zeziphi iimpawu zokukhanya kwemagnesium oxide?

Khaphukhaphu kwaye bulky, i-amorphous powder emhlophe. Ayinamavumba, ayinambitheki kwaye ayinetyhefu.

Yintoni uxinizelelo lokukhanya kwemagnesium oxide? Ubuninzi be-3.58g / cm3. Ayinyibiliki emanzini acocekileyo nakwizinyibilikisi eziphilayo, kwaye ukunyibilika kwayo emanzini kuyanda ngenxa yobukho bekhabhoni dayokhsayidi. Inokuchithwa kwisisombululo seetyuwa kunye ne-ammonium. Iguqulwa ibe ziikristale emva kokushisa okuphezulu. Kwimeko yekhabhon dayoksayidi esemoyeni, i-magnesium carbonate ityiwa kabini iyenziwa.

Umcimbi onzima uhambelana nomthamo kwaye umhlophe okanye umgubo we-beige. Kulula ukudityaniswa kunye namanzi, kwaye kulula ukufunxa ukufuma kunye nekhabhon diokside emoyeni ocacileyo. Kulula ukwenza ijeli kwaye iqine xa ixutywe nesisombululo se-magnesium chloride.
