Cov nyhuv ntawm graphite ntxiv rau ntawm magnesia carbon cib

Acid refractory tsuas yog tsim los ntawm tridymite, cristobalite thiab ib qho me me ntawm cov seem quartz thiab iav theem.

Microstructure ntawm magnesia cib

Carbon bricks yog dav siv tsis tau tsuas yog nyob rau hauv metallurgy kev lag luam, tab sis kuj nyob rau hauv txhuas electrolysis hlwb.
