Abstract
Alumina-20 vol% zirconia (12 mol% ceria) composite powder has been extruded using boehmite (AlOOH) as an extrusion aid. A higher order of homogeneity of the constituent phases has been achieved in this work by controlling the pH of flocculation at 8.5. Sintering was carried out at 1600 degrees C. Th e microstructural evaluation confirms uniform distribution of different pha ses throughout the specimen. The possibility of boehmite being used as extr usion aid to alumina based ceramics is highlighted. (C) 1998 Published by E lsevier Science Limited and Techna S.r.l.
