Abstract:
OBSERVATIONS OF SPHERE-TO-PLATE BONDING OF VACUUM-REDUCED, MONOCRYSTALLINE RUTILE WERE CARRIED OUT OVER THE TEMPERATURE RANGE 1200 TO 1275 C. The rate law governing the interfacial growth between sphere and plate indicat d that the predominate mechanism of material transport in this sintering process was volume diffusion. In the light of the reasonably satisfactory agreement between the oxygen self-diffusion coefficients calculated from the pr sent sintering data and those directly observed by Haul and Just utilizing an isotopic exchange technique, it was indicated that oxygen ion diffusion is the ratedetermining step in the sintering experiments described.
