The influence of carbon on the microstructure of 98% MgO refractories was investigated by quantitative ceramography after selected heat treatments. The dihedral angle of the silicate phase at the periclase grain boundaries inside the grain of the refractories containing carbon is increased after high temperature coking. The distribution of dihedral angles measured on polished sections is broader than derived mathematically, however the trends of the true dihedral angles, the medians of the measured distributions, are followed also by the whole distributions. Reasons for this broadening of the distributions and for the influence of carbon on the micro-structure of periclase refractories are discussed.
