Relaxor behaviour of K <inf>0.5</inf>Bi <inf>0.5</inf>NbO <inf>3</inf>- BiScO <inf>3</inf> ceramics

Dielectric properties of (1 - x)K 0.5 Bi 0.5 TiO 3 - xBiScO 3 ceramics have been studied for compositions x < 0.5. Single-phase solid solutions occurred for compositions x < 0.25. A frequency-dependent dielectric relaxation was observed, consistent with relaxor behaviour. This gave r...
