(2). The crystallization fraction and rate of tetragonal
Nd2Si2O7 were determined based on the exothermic
DTA data. The experimental value of the maximum
crystallization rate was similar to the theoretical value.
(3). The kinetics of tetragonal Nd2Si2O7 crystallization
from polymeric xerogels was investigated under nonisothermal
conditions using the Kissinger method.
The activation energy of tetragonal Nd2Si2O7 crystallization
was 673 kJ/mol.
(4). The crystallization process of tetragonal Nd2Si2O7
could involve the nucleation and three-dimensional
growth that follows the diffusion-controlled mechanism
when the nucleation rate increased.
