Potassium niobate (KNbO3; KN) is a well known ferroelectric material with perovskite structure. Recently, this crystal has been given much attention as an environmentally friendly material as well as surface acoustic waves (SAW) and bulk acoustic wave (BAW) devices. It is, however, very difficult to grow KN crystals because KN melts incongruently. In this paper, KN crystal fibers have been successfully grown from stoichiometric melt by micro pulling down (μ-PD) method, and parameters necessary for the reproducible growth of KN fiber have been revealed. Dielectric properties of grown fiber crystal were also measured.
