Izitena zeMagnesia zinomxholo we-magnesium oxide ongaphezulu kwe-90% kwaye zamkele i-periclase njengenqanaba lekristale eliphambili. Izitena zeMagnesite zinokwahlulwa zibe ziindidi ezimbini zeZitena ezitshisiweyo zeMagnesia kunye neChemical Bonded Magnesite Brick. Izitena zeMagnesite zinomsebenzi ogqwesileyo wokuqina okuphezulu kobushushu obuphezulu bomatshini kunye nokuzinza kwevolumu. Kwaye inokusebenza kubushushu obuphezulu be-1750 ℃, izitena zeMagnesite ziimveliso ezifanelekileyo kwisicelo seglasi yomlilo.
Izitena zeMagnesia zinokuhlelwa zibe ziindidi ezimbini: izitena ezitshisiweyo zemagnesite kunye nezitena ezidityaniswe neekhemikhali. Izitena ezitshisiweyo ze-magnesite zenziwe ngezinto eziluhlaza ze-periclase, emva kokuba zitshiswe nge-1550 ~ 1600 ℃ ubushushu obuphezulu ngokutyumza, ukuxuba, ukunyibilika kunye nokubumba. Iimveliso zococeko eziphezulu zineqondo lobushushu elitshisiweyo elingaphezulu kwe-1750℃. Isitena se-magnesite esingatshiswanga senziwe ngokongeza i-agent yekhemikhali efanelekileyo ngokunyibilika, ukubumba kunye nokomisa.
Ngenxa yokwakheka kweekhemikhali ezahlukeneyo zezitena ze-magnesia, ezinokuthi zihlulwe kwiintlobo ezahlukeneyo, kwaye zonke ezi zitena ziveliswa nge-sintering. Ngokusekwe kwimathiriyeli ekrwada ehlukeneyo, izitena zemagnesia zinokuhlelwa ngokwezintlu zilandelayo:
Isitena se-magnesia esiqhelekileyo: ilitye le-magnesite elidityanisiweyo.
Ibhondi ethe ngqo yesitena semagnesia: ubunyulu obuphezulu be-sintered magnesite.
Isitena se-Forsterite: i-peridotite
Isitena seMagnesia calcia: iMagnesite ene-sintered equlethe i-calcium ephezulu.
I-Magnesia silica isitena: ilitye le-silicon ephezulu ye-sintered magnesite.
I-Magnesia chrome isitena: i-magnesite edibeneyo kunye nentsimbi ye-chrome.
Isitena se-alumina ye-Magnesia: ilitye le-magnesite edibeneyo kunye ne-Al2O3.

Izitena ze-Magnesite zifanelekile kuzo zonke iintlobo zokushisa eziphezulu, ezifana nezixhobo ze-metallurgical. Ukongeza, izitena ze-magnesia zisetyenziswa ngokubanzi kwezinye izixhobo ezishushu, ezifana ne-hyperthermia tunnel kiln, i-lining ye-rotary sement kiln, i-oven the furnace ezantsi kunye nodonga, igumbi lokuvuselela i-glass furnace, isithando sombane esisezantsi kunye nodonga kunye nokunye.
Umenzi we-RS refractory ngumenzi wezitena ze-magnesia e-China, unokubonelela ngezitena eziphezulu ze-magnesite kuwe. Ukuba unemfuno yezitena ze-magnesia, okanye unemibuzo malunga nezitena ze-magnesia malunga nezikhombisi zomzimba kunye neekhemikhali, nceda uqhagamshelane nathi mahhala, ukuthengisa kwethu kuya kuqhagamshelana nawe ngokukhawuleza.
