| Abstract: | This paper studies the aluminium carbide,a recognized harmful substance formed in prep- aration of magnesia carbon bricks or regenerated magnesia carbon bricks. The formation mechanism of aluminium carbide is determined in the range of thermal treated temperatures. The paper also studies the effects of thermal treated temperatures and graphite additions on the formation of aluminium carbide（ A14C3 ）. |
