| dc.description | The sintering behavior of La0.9Sr0.1Ga0.8Mg0.2O3-?? oxide-ion conductor was systematically investigated by
thermodilatometry. The shrinkage data obtained with heating rates of 4, 7, 10 and 12 ??C min???1 were analyzed by
the constant rate of heating model and by construction of the master sintering curve. Validation of the master
sintering curve was carried out by measurements of density in conventionally sintered specimens. Slight anisotropy
of shrinkage data was found and changes to the basic equation of density was proposed to account for
this effect. Plotting the data determined by the constant rate of heating model versus density allowed an easy
identification of the density range of constant activation energy. The activation energy (865 kJ mol???1) obtained
from the master sintering curve correlates quite well with that (874 kJ mol???1) obtained by the constant rate of
heating model. | |
