Glass and Ceramics (English translation of Steklo i Keramika) | Year: 2013
A new approach to obtaining a functional glass ceramic based on potassium niobate from an amorphous precursor, obtained by rapid cooling of the melt containing small additions of the glass former SiO2, is examined. The results indicate that there is promise in the glass ceramic technology, which ensures the formation of cubic KNbO3 crystals of almost ideal habitus whose flat grains surrounded by thin, composition-regulated glass interlayers can stick to one another. The ceramic KNbO3 obtained by the glass ceramic technology differs beneficially from its conventional analog by low tanä in the entire range of existence of the ferroelectric phase (below 410 C), which determines its advantage for a host of applications. © 2013 Springer Science+Business Media New York.
