Lebenka Magnesia wuxuu leeyahay in ka badan 90% magnesium oxide wuxuuna qaataa periclase marxaladda ugu weyn ee crystalline. Lebenka Magnesite waxaa loo qaybin karaa laba qaybood oo ah lebenka Burnt Magnesia iyo lebenka kiimikada ee isku xiran ee Magnesite. Lebenka Magnesite wuxuu leeyahay waxqabad aad u wanaagsan oo leh awood farsamo oo heer sare ah iyo xasillooni mugga. Waxayna u adeegi kartaa heerkulka sare ee 1750℃, lebenka Magnesite waa badeecooyin ku habboon isticmaalka foornada galaaska.
Sifooyinka lebenka Magnesia
- Refractorins-ka aadka u sarreeya,
- iska caabbinta slag-ka alkaline,
- Iska caabbinta nabaad-guurka iyo ka-hortagga oksaydhka oo aad u fiican,
- Diidmo sare oo culays saaran,
- Awood farsamo oo sare,
- Xasiloonida mugga heerkulka sare.
Habka Wax-soo-saarka Lebennada Magnesia
Lebenka Magnesia waxaa loo kala saari karaa laba nooc: lebenka Magnesite ee gubtay iyo lebenka Magnesite ee kiimikada ku xiran. Lebenka Magnesite ee gubtay waxaa laga sameeyaa walxo cayriin ah oo periclase ah, ka dib marka la shido heerkul sare oo ah 1550 ~ 1600℃ iyada oo loo marayo burburinta, isku darka, dhalaalinta iyo qaabaynta. Badeecadaha saafiga ah ee sarreeya waxay leeyihiin heerkul guban oo ka badan 1750℃. Lebenka Magnesite ee aan gubin waxaa laga sameeyaa ku darista wakiil kiimiko ah oo ku habboon iyada oo loo marayo dhalaalinta, qaabaynta iyo qalajinta.
Kala soocidda lebenka Magnesia
Sababo la xiriira isku-dhafka kiimikada ee kala duwan ee lebenka magnesia, kaas oo loo kala saari karo noocyo kala duwan, dhammaan lebenkanna waxaa lagu soo saaraa sintering. Iyada oo lagu saleynayo walxo cayriin oo kala duwan, lebenka magnesia waxaa loo kala saari karaa qaybaha soo socda:
Dhagax birlab ah oo birlab ah: dhagax birlab ah oo birlab ah.
Leben birlab ah oo birlab ah: birlab birlab ah oo saafi ah oo saafi ah.
Lebenka Forsterite: peridotite
Magnesia calcia leben: Magnesite sintered ah oo ka kooban kalsiyum sare.
Dhagaxa silica ee Magnesia: dhagaxa silica ee silikoon sare leh.
Leben bir ah oo ...
Lebenka alumina ee Magnesia: dhagaxa magnetite ee sintered iyo Al2O3.
