Resumen:
We extend the Clusters model to account for the presence of
rigid inclusions and use it to analyze the experimental sintering
kinetics of composites of 60SiO2 . 24B2O3 . 16Na2O glass particles
and zirconia fibers. We followed the densification kinetics
of such composites as a function of the particle size, volume
fraction of fibers, fiber to pore size ratio, temperature, and time
of thermal treatment. The parameters of the extended Clusters

of thermal treatment. The parameters of the extended ClustersClusters
model are the glass particle size distribution and shape factor,
the fiber volume fraction and radii, the glass viscosity and surface
tension, the number of nucleating sites per unit surface, and
the crystal growth rate in the parent glass. Hydrostatic tensions
caused by the fibers were also included in the calculations. The
modified Clusters model with only one adjustable parameter,
which is largely dominated by viscosity but also includes particle
shape, allowed us to account for the effect of surface crystallization
and fiber content as inhibitors of densification and
successfully describe the sintering kinetics of the studied
composites.
