A new member in the tungsten-bronze family of ferroelectric lead- potassium-niobate PKN, with general formula PB1-xK2xNb2O6, has been grown as bulk single crystal. Growth of PKN with charge composition x 0.23 has been achieved using the Czochralski technique of crystal pulling. Large diameter boules were grown in platinum crucibles at temperatures between 1280 deg C and 1300 deg C. Crystallographic studies were conducted using X-ray diffraction techniques. The samples were characterized for ferroelectric properties between 25 deg C and 600 deg C and for optical absorption. This paper presents the crystal synthesis and the results of ferroelectric and optical characterization.
