A homogeneous KNbO 3 (KN) phase was formed in specimens that were sintered at 1020 °C and 1040 °C, without formation of the K 2 O-deficient secondary phase, indicating that the amount of evaporation of K 2 O during sintering was very small. However

Crystalline (Zr,Ti) 0.85 (Ca,Sr) 0.15 O 1.85 (ZTCS) films were grown on a Pt/Ti/SiO 2 /Si substrate at various temperatures by using rf-magnetron sputtering. The ZTCS films had a cubic stabilized zirconia structure. The dielectric constant ( k ) of t

Dielectric and piezoelectric properties of CuO-added KNbO3 (KN) ceramics were investigated. The CuO reacted with the Nb2O5, formed a CuO–Nb2O5-related liquid phase during the sintering, and assisted the densification of the KN ceramics at low tempe

A homogeneous Bi12TiO20 phase was developed in a specimen that was calcined at 700°C without the formation of a secondary phase. A small amount of the Bi12TiO20 phase melted during sintering and assisted the densification of the specimen. The Bi2O3

The Microstructure and microwave dielectric properties of Bi2O3-deficient Bi12SiO20 ceramics were investigated. A small amount of unreacted Bi2O3 phase melted during sintering at 825°C and assisted with densification and grain growth in all samples.
