Characterization of lead scandium niobate ceramics prepared by precipitation method

Abstract

The synthesized monosized PSN complex precursor powder was produced using the methods of the controlled hydrolysis of Nb(OC{sub 2}H{sub 5}){sub 5} and the growth of scandium and lead carbonates on the as-hydrolyzed Nb{sub 2}O{sub 5} particle surface. Calcining the carbonates to oxides and sintering at different temperatures with various cooling rates produced dense ceramics. The relation between dielectric relaxation character and structural ordering of the sintered PSN ferroelectric ceramics was investigated.
