Abstract
High phase purity barium metazirconate powders have been synthesized from a modi®ed
solid-state reaction. Reactive powders consisting of submicron particles and narrow particle
size distribution were obtained by heating a 1:1 molar mixture of barium nitrate and zirconyl
nitrate at 8008C up to 8 h. Simultaneous thermal analysis (TG-DTA) assisted in elucidating
the probable reaction pathways leading to the formation of the target compound in the BaO±
ZrO2 system. Systematic structural and microstructural characterization on the green powders
and the compacts sintered up to 17008C were carried out. A two-stage sintering schedule
