Zusammenfassung:Hydrophilic graphite-base powder is provided wherein hydrophilic small particles of such as silicon carbide or silica are mixed with a graphite powder and the small particles are attached to each surface of the graphite particles by performing a mechanical impact treatment in a high-speed gas flow. By combining the graphite-base powders with refractory compound powders of such as magnesia or alumina to be a powder mixture for monolithic refractories containing graphite, a formed body of the powder mixture having a large bulk density can be provided and a service life thereof is comparable to that of a shaped refractory, and labor and energy necessary for the production process and the operation are saved.
