Microstructure ntawm magnesia cib

Lub microstructure ntawm magnesia bricks tiag tiag yog kev sib xyaw ntawm magnesia microstructures. Lub microstructure ntawm magnesia bricks ua nrog ib tug raw khoom yog qhov yooj yim tshaj. Magnesia cib ua los ntawm British seawater magnesia uas yuav luag tsis muaj silicate tsuas yog rau pores hauv matrix. Intracrystalline thiab intercrystalline micropores ntawm periclase yog cov yam ntxwv ntawm cov qauv. Kev tsim cov magnesia bricks tsuas yog tso siab rau sintering ntawm cov kua theem hauv magnesia nplua hmoov matrix kom ua tiav kev sib xyaw ntawm cov khoom. Yog li ntawd, cov ntaub ntawv raw nrog siab purity yog qhov nyuaj rau sinter, thiab seawater magnesia bricks yuav tsum tau ua nyob rau ntawm qhov kub ntawm 1700 ~ 1800 degree los yog siab tshaj 1850 degree. kub raug rho tawm haujlwm. Cov cib nrog ntau silicate (CMS) tuaj yeem sintered ntawm 1500 ~ 1600 degree. Yog li ntawd, feem ntau magnesia bricks yog ntom, thaum seawater magnesia bricks yog ntxeem tau. Txawm li cas los xij, nws qhia qhov sib txawv ntawm cov txiaj ntsig ntawm cov khoom siv hluav taws xob kub siab. Piv txwv li, lub softening kub ntawm dej hiav txwv magnesia bricks nyob rau hauv load yog siab tshaj 1700 degree; Feem ntau, sintered magnesia bricks yog 1500 ~ 1600 degree. High-purity magnesia bricks tsim tawm txawv teb chaws feem ntau siv seawater magnesia los yog seawater magnesia ua ke nrog fused magnesia.
