Izitena zekhabhoni yeMagnesia luhlobo lwekhabhoni engatshiyo edityanisiweyo, eyenziwe nge-magnesium oxide yealkaline oxide enendawo yokunyibilika ephezulu (2800 ℃), kunye nezinto zekhabhoni ezinendawo yokunyibilika ephezulu ekunzima ukukhukuliseka ngenxa ye-slag yesithando somlilo. imathiriyeli ekrwada, kwaye yongeza zonke iintlobo ze-non-oxides additives kunye ne-carbon binding agent. Izitena zekhabhoni yeMagnesia zineempawu ze-porosity ephantsi, ukumelana nokhukuliseko lwe-slag, ukuxhathisa ukothuka kwe-thermal kunye namandla aphezulu obushushu obuphezulu. Njengohlobo lwe-refractory edibeneyo, izitena zomlilo ze-magnesia zisebenzisa i-slag corrosion ye-magnesia kunye ne-thermal conductivity ephezulu kunye nokwandiswa okuphantsi kwekhabhoni ngokufanelekileyo, kunokwenza umonakalo omkhulu wokunganyangeki kwe-spalling ye-magnesia.
Izitena zekhabhoni ye-Magnesia amacandelo aphambili yi-magnesium oxide kunye nekhabhoni, apho umxholo we-magnesium oxide yi-60 ~ 90% kunye ne-carbon content yi-10 ~ 40%. Olu hlobo lwemathiriyeli lwenziwe ngobunyulu obuphezulu be-magnesia, i-carbon material, i-tar, i-pitch okanye i-resin njengemathiriyeli ekrwada ngokubhaka okuphezulu kweqondo lokushisa. Ke izitena zekhabhoni zemagneti zineempawu zokumelana ne-slag corrosion, ukuxhathisa ukothuka kwe-thermal, i-thermal conductivity kunye njl.
Ngokweendlela zokuxuba ezibandayo kunye ne-agent ebophelelayo yetela iba lukhuni kwaye ifumane amandla ayimfuneko, ngaloo ndlela yenza i-isotropous vitric carbon. Izitena zekhabhoni yeMagnesia zenziwe nge-agent ebopha i-pitch, enobushushu obuphezulu beplastiki ngenxa yokwenza i-anisotropic graphitization coke structure kwinkqubo ye-pitch carbonation. Olu hlobo lwekhabhoni alubonisi thermoplasticity enokususa ngokufanelekileyo inani loxinzelelo kwinkqubo yokudubula okanye ukusebenza.

Izitena zekhabhoni ze-Magnesia zisetyenziselwa ubukhulu becala i-linings of converter, i-oven-arc furnace kunye nesithando sombane esithe ngqo se-arc, umgca we-slag we-ladle yensimbi kunye nesinye isikhundla. kwaye ingasetyenziselwa isithando somlilo esisisiseko se-oksijini, umgca we-slag wesithando somlilo kunye nendawo eshushu ye-arc yombane.
Umzi-mveliso we-RS refractory njengomnye we-oven kiln magnesite izitena zekhabhoni ezikhokelayo, unokubonelela ngezitena zekhabhoni ze-magnesia kubathengi abanobuchwephesha beenjineli, iteknoloji yemveliso ephuculweyo kunye nelungileyo ngaphambi kokuthengisa kunye nenkonzo emva kokuthengisa. Umzi-mveliso we-RS refractory ukhethekileyo kwizitena zomlilo ze-carbon magnesite ngaphezu kweminyaka engama-20. Ukuba unemfuno ethile yesitena se-carbon ye-magnesia, qhagamshelana nathi simahla, ukuthengisa kwethu kuya kukuphendula okokuqala.
