Resumen

TROMBINI, V.; BRESSIANI, A. H. A.; PALLONE, E. M. J. A.  y  TOMASI, R.. Optimization of the milling and drying processes of alumina/TiC powder obtained by reactive milling. Cerâmica [online]. 2011, vol.57, n.344, pp. 416-421. ISSN 0366-6913.  http://dx.doi.org/10.1590/S0366-69132011000400007.

Agglomerates in ceramic powders often cause heterogeneities and defects in the final ceramic product, due to differential densification of the agglomerates during the sintering stage. Hence, control of the processing steps is important to form ceramic bodies without agglomerates and with a homogeneous microstructure. In this study, the processing conditions to reduce aggregate formation during high-energy milling and control of the powder drying step were evaluated to attain a microstructure consisting of small grains and a homogeneous distribution of TiC inclusions in the matrix.

Palabras clave : alumina; TiC; drying; high energy milling.
