Measurements of initial sintering shrinkage of CaAl407 are reported in the temperature range 1380-1480 deg C. The particle size chosen was -45 micron and the soaking periods were from 10 to 180 minutes. The time dependance of shrinkage indicated that the grain boundary diffusion is the dominant mechanism of sintering. The activation energy for the sintering of CaAl407 was found to be 151.0 kcal.mol-1.
