Proceedings ofISAF2007: GrowthofLeadZirconate Titanate Nano-Sized Tubes

Leadzirconate titanate (PZT)isasolid structures, suchasporousanodic alumina (A.A.) solution system withhighspontaneous polarization, membranes orthinfilms. However, theferroelectric dielectric permittivity andpiezoelectric coefficients. In materials growninthisprocess areamorphous and thecurrent study, we havegrownleadzirconateshouldbe annealed tore-crystallize thedesired titanate nanotubesthrough thetemplate-based ferroelectric phase.When amorphousPZT synthesis process.
