Notes:
Sintering behavior and mechanism of barium titanate powders prepared by high-gravityreactive precipitation (HGRP) process has been investigated by a dilatometer. The mean particlesize of barium titanate powders prepared by HGRP was about 80 nm. Pure BaTiO3 pellets weresintered at a constant heating rate of 2.0 K/min and the temperature of shrinkage-onset for pelletwas 1060°C. The maximal shrinkage was 165um and the maximum of shrinkage rate was 8.0 x 10-3/ min at 1170°C. The sintering mechanism for the initial stages of sintering was determined byisothermal dilatometric measurements and was found to be viscous flow
