KNbO3 single crystals are grown by the self-flux method using K2CO3 as a flux, but often suffer from discolouration. In this work, KNbO3 single crystals were grown by the flux method using KBO2 as a flux. KNbO3 powder was prepared by the solid-state

This paper suggests future research directions in grain growth and related subjects. A discussion on the available mechanisms of grain growth has led to an emphasis on the mixed control mechanism of boundary migration and grain growth. The mixed cont

Ceramics of composition 0.75(Na1/2Bi1/2)TiO3-0.25SrTiO3 (NBT-25ST) show a giant electric field-induced strain, making them attractive for actuator applications. Single crystals generally have improved piezoelectric properties over their ceramic count

Single crystals of 0.75(Na0.5Bi0.5)TiO3-0.25(Sr0.7Ca0.3)TiO3 (NBT-25SCT) were grown by top-seeded solid state crystal growth. X-ray diffraction of a polycrystalline ceramic sample and Raman scattering of a single crystal reveal that rhombohedral symm

The effect of sintering atmosphere (O2, air, N2, N2-5% H2, and H2) on the densification, grain growth, and structure of KNbO3 was studied. KNbO3 powder was prepared by solid state reaction, and samples were sintered at 1040 °C for 1−10 h. The samp
