Fabrication and electrical properties of Pb(Co<inf>1/3</inf>Nb<inf>2/3</inf>)O<inf>3</inf> ceramics

Pb(Co1/3Nb2/3)O3 (PCN) ceramics have been produced by sintering PCN powders synthesized from lead oxide (PbO) and cobalt niobate (CoNb2O6) with an effective method developed for minimizing the level of PbO loss during sintering. Attention has been focused on relationships between sintering condition...
