Abstract
Dense round rods are obtained by placing an uncompacted particle mass into a mold containing a cavity of a predetermined geometry. The particle mass is subjected to a heating schedule wherein entrapped gases are permitted to pass off during an initial period of the schedule and during a second period of the schedule at least 75% liquid phase is formed, whereby surface tension forces cause the particle mass top portion to attain a hemispherical shape. The heated mass is permitted to cool and a round product is obtained.
