A new approach to the preparation of functional glass-ceramics based on potassium niobate from an amorphous precursor obtained by rapid cooling of a melt containing small additives of the SiO 2 glass-former is considered. The KNbO3 glass-ceramics obtained by the glass-crystalline technology favorably differs from its traditional analogue by the reduced values ??of tan ?; in the entire region of existence of the ferroelectric phase (below 410 ° C), which determines its advantage for a number of applications.
