Fused quartz
Hauv Si thiab FeSi ntau lawm, qhov tseem ceeb ntawm Si yog SiO2, nyob rau hauv daim ntawv ntawm quartz.Cov tshuaj tiv thaiv nrog SiO2 tsim SiO roj uas txuas ntxiv nrog SiC rau Si.Thaum lub sij hawm cua sov, quartz yuav hloov mus rau lwm qhov kev hloov kho SiO2 nrog cristobalite raws li qhov kub thiab txias.Transformation rau cristo ...Nyeem ntxiv -
Kev cuam tshuam ntawm mineralizers ntawm cov khoom ntawm cov ntaub ntawv ceramic
Magnesium aluminium spinel (MgAl2O, MgO·Al2Oor MA) muaj qhov zoo tshaj qhov kub thiab txias txhua yam khoom, zoo heev tev thiab corrosion kuj.Nws yog qhov zoo tshaj plaws kub kub ceramic hauv Al2O-MgO system.Qhov zoo tshaj plaws kev loj hlob ntawm calcium hexaaluminate (CaAl12O19, CaO·6AlO...Nyeem ntxiv -
Puas yog cov khoom siv hluav taws xob dawb huv tuaj yeem siv los tsim cov mullite ceramics?
Qee qhov kev lag luam pov tseg tau pom tias muaj txiaj ntsig zoo hauv kev tsim cov mullite ceramics.Cov khoom siv khib nyiab no yog nplua nuj nyob hauv qee cov hlau oxides xws li silica (SiO2) thiab alumina (Al2O3).Qhov no muab pov tseg lub peev xwm los siv los ua cov khoom pib rau kev npaj mullite ceramics.Cov p...Nyeem ntxiv
