Unlike in the solid-state reaction activated by calcination at an intermediate temperature, intermediate phases, such as PbTiO3, were not observed with increasing degree of mechanical activation prior to the formation of perovskite 0.9Pb(Zr0.52Ti0.48)O3-0.1BaTiO3 phase. This suggests that the nucleation and subsequent growth of perovskite crystallites in the activated oxide composition are not a result of the interfacial reactions that normally occur in the temperature-driven solid-state reaction. The mechanical activation-derived powders can be sintered to a relative density of||Source Title:||Applied Physics A: Materials Science and Processing||URI:||http://scholarbank.nus.edu.sg/handle/10635/107091||ISSN:||09478396||DOI:||10.1007/s003390051027|
