It is shown that seeding a commercial boehmite sol with crystallographically suitable seeds reduces both the crystallization temperature for the final alpha-Al2O3 phase and the sintering densification temperature. The seeding component was a tailored combination of delta- and alpha-alumina particles in nanometre and micrometer ranges, respectively, dispersed in water. Electrophoretic deposition (EPD) provided a quick, simple and cost-effective processing route to prepare dense monolithic alumina ceramics from the seeded boehmite suspensions. EPD-formed green bodies could be sintered and densified at temperatures as low as 1250 degreesC for 2 h. (C) 2002 Elsevier Science Ltd and Techna S.r.l. All rights reserved.
