Waxqabadka ugu weyn ee leben magnet

a. Dib -u -noqoshada

Sababtoo ah barta dhalaalka ee periclase (MgO) crystals waa mid aad u sarreeya, oo gaaraya 2800 ℃, dib-u-celinta lebenka magnesia waa tan ugu sareysa ee lebennada guud ee dib-u-celinta, badanaaba ka sarreeya 2000 ℃.

b. Xoog qaab dhismeedka heerkulka sare

Awoodda heerkulka sare ee lebenka magnesia ma fiicna, heerkulka bilawga ah ee jilcinta ee culeysku waa inta u dhaxaysa 1500 iyo 1550 ° C, taas oo ka hooseysa 500 ° C ka hooseeya refractoriness.

c. Iska caabin adag

Lebenka Magnesium waa maaddooyinka soo celisa alkaline waxayna leeyihiin iska caabin xoog leh oo ku wajahan caleenta alkaline sida CaO iyo FeO. Sidaa darteed, inta badan waxaa loo isticmaalaa sida walxaha dhogorta leh ee foornooyinka dhalada alkaline, laakiin iska caabintooda caarada aashitada waa mid aad u liidata. Lebenka Magnesium lama xiriiri karo maaddooyinka dib-u-celinta aashitada, waxay kiimiko ahaan isu falcelinayaan midba midka kale oo daxaloobay in ka badan 1500°C. Sidaa darteed, lebenka magnesia laguma qasi karo leben silica.

d. Deganaanshaha kulaylka

Xasiloonida kulaylka ee lebenka magnesia waa mid aad u liidata, waxayna kaliya u adkeysan kartaa qaboojinta biyaha 2 ilaa 8 jeer, taas oo ah faa’iido darro weyn.

e. Degganaanshaha mugga

Isku-dhafka balaadhinta kulaylka ee leben magnesia waa weyn yahay, isku-dhafka fidinta tooska ah ee u dhexeeya 20 ~ 1500 ℃ waa 14.3 × 106, markaa kala-goysyada ballaarinta ku filan waa in laga tago inta lagu jiro habka wastaadda.

f. Dhaqdhaqaaqa kulaylka

Dhaqdhaqaaqa kulaylka ee lebenka magnesia waa dhowr jeer oo leben dhoobo ah. Sidaa darteed, lakabka sare ee foornada ee ay dhiseen lebenka magnesia waa in guud ahaan lahaado lakabka kuleylka ku filan si loo yareeyo luminta kulaylka. Si kastaba ha ahaatee, kulaylka kulaylka ee leben magnesia ayaa hoos u dhacaya heerkulka sii kordhaya.

g. Biyo-bax

Osaydhka magnesium-ka ee aan ku filnayn ayaa la falgala biyaha si ay u soo saaraan falcelinta soo socota: MgO+H2O→Mg(OH)2

Tan waxa loo yaqaan falcelinta fuuq-celinta. Dareen-celintan awgeed, mugga ayaa ku fiday 77.7%, taasoo keentay dhaawac halis ah lebenka magnesia, taasoo keenta dildilaacyo ama qulqulo. Lebenka magnesia waa in laga ilaaliyaa qoyaanka inta lagu jiro kaydinta.
