Magnesia-carbon brick
The present invention improves the density (reduces the porosity) of one layer in a magnesia-carbon brick and provides a magnesia-carbon brick having higher durability than ever before. The magnesia-carbon brick according to the present invention comprises a magnesia raw material and graphite, wherein the graphite is contained in an amount of 3 to 25 mass% inclusive relative to the total amount of the magnesia raw material and the graphite, the magnesia raw material is contained in an amount of 75 to 97 mass% inclusive relative to the total amount of the magnesia raw material and the graphite, and the apparent porosity of the magnesia-carbon brick is 7.8% or less after the magnesia-carbon brick is subjected to reduced firing at 1400 not C for 3 hours.
