MAGNESIA-CARBON BRICK
In the present invention, the attempt was made to increase the denseness (lowering the porosity) of a magnesia carbon brick furthermore thereby providing the magnesia carbon brick having high durability never found in the past. The magnesia carbon brick of the present invention comprises a magnesia raw material and a graphite, wherein the magnesia carbon brick contains the graphite with amount of in the range of 3% or more by mass and 25% or less by mass and the magnesia raw material with amount of in the range of 75% or more by mass and 97% or less by mass, the both amounts being relative to total amount of the magnesia raw material and the graphite; and an apparent porosity thereof after reductive firing for 3 hours at 1400°C is 7.8% or less.
