| dc.description | Alumina-mullite composites with low shrinkage can be made by reaction bond using
mixtures of alumina, aluminum and silicon carbide. In this work, an alternative route is used to
produce alumina composites with low shrinkage. Here alumina samples containing additions of 10
and 20 wt% of a preceramic polymer were warm-pressed and treated in the range of 900 -1500??C to
produce alumina based composites. The obtained composites were analyzed by linear shrinkage and
compared to pure alumina samples sintered at the same temperature range. It were also evaluated
the density variation and crystalline phases formed during heat treatment of alumina composites.
Results showed that alumina-silicon oxycarbide and alumina-mullite composites were obtained with
lower shrinkage than pure alumina samples. | |
