摘要:Abstract: Nanostructured lanthanum zirconate powders were successfully prepared by polyethylene glycol hydrothermal method at relatively lower sintering temperature. XRD and SEM were carried out to study the phase structure and grain size of the lanthanum zirconate. It can be concluded that precursor of lanthanum zirconate can be obtained after hydrothermal synthesis at 498 K and nanostructured lanthanum zirconate can be obtained after sintered at high temperature (above 1173 K). The grain size of lanthanum zirconate is about 30 nm after sintered at 1173 K - 1373 K. Meanwhile, the grain size is as small as 60 nm after sintered at 1673 K for 2 h.
