ETA of nanocomposite xerogel powders

Alumina-silicon carbide nanocomposite ceramics are known for their high strength. This article reports a study of the thermal behavior of Al{sub 2}O{sub 3}-SiC composite xerogel powders used as the feed material in the manufacture of ceramics by high-temperature hot pressing. Emanation thermal analysis (ETA) was used with traditional differential thermal analysis (DTA) to describe changes in the morphology and texture of the nanocomposite powders and the ceramics obtained from these powders.
