Abstract:

This paper studies the aluminium carbide，a recognized harmful substance formed in  preparation  of magnesia carbon bricks or regenerated magnesia carbon bricks.The formation mechanism of aluminium carbide is determined within 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（Al4C3）.
