Cov khoom lag luam refactory ncaj qha nrog spinel thiab magnesia chromite raws li lub ntsiab crystal theem. Qhov cib no yog tsim los ntawm cov tshuaj tsw qab siab heev thiab chromite nrog Sio2 tsawg dua 2% raws li cov ntaub ntawv raw, thiab yog sintered ntawm qhov kub.
Cov khoom raug rho tawm ntawm 1750 degree muaj qib siab heev ntawm kev sib tham ncaj qha. Siv nyob rau hauv lub cub hluav taws xob kom tiv thaiv kev ntxhov siab loj thiab yuag yaig, nws yuav luag hloov kho cov pob zeb sib tsoo.
Cov Qauv Ua Ntej Maglesia Chrome Cib yog ib yam khoom ua los ntawm high-purity sintered lossis ua kom siab sugices magnesia xuab zeb thiab chromium tsom ua cov ntaub ntawv raw.
Cov khoom no muaj ob peb impurities thiab raug rho tawm haujlwm thaum kub. Lub iav theem yog feeb txog thaj tsam ntawm thaj tsam ntawm cov Crystal Crystal, thiab theem siv lead ua yog ncaj qha nrog cov Crystal theem. Cov kev ua tau zoo ncaj qha ua ke. Cib sintsing belongs rau cov khoom-qib tsevneeg tsev, yog li cov khoom muaj zog, oxidation tsis kam, muaj zog hlau permeability, thiab ruaj khov tso rau ntawm qhov kub siab. Haum rau kev ntsuas cov txheej txheem qhuav cement ceeb, tooj liab ua ke, kho kom ruaj khov,
