Abstract
A more pressable composition for making graphitic refractory brick from oxide aggregate with a carbon bond is obtained when the refractory oxide aggregate is substantially all coarser than 0.15 mm (+100 mesh), preferably coarser than 0.2 mm (+65 mesh), and most preferably coarser than 0.4 mm (+35 mesh), and the matrix is entirely carbonaceous material, such as graphite, particularly flake graphite, resin, particularly a phenol formaldehyde resin, together with such other carbonaceous materials as carbon black, calcined coke, anthracite, and the like.
