摘要：

A new K2O-SrO-Nb2O5-B2O3-Al2O3-SiO2 (KSN-BAS) glass-ceramic system has been prepared by conventional controlled-crystallization method. The crystallization behavior and dielectric properties of the glass-ceramics were investigated. The X-ray diffraction analysis showed that the KSr2Nb5O15 and SrNb2O6 phases with tungsten bronze structure were precipitated from the glass matrix, as the crystallization temperature increased, the AlNbO4 phase was observed. The microstructure observed the sizes of grains became larger and presented the grain reunion severely. The dielectric constants of all the samples exhibited excellent stability from -90 degrees C to 120 degrees C and low dielectric losses less than 0.03. A maximum dielectric constant was obtained at annealing of 900 degrees C. The dielectric breakdown strength (BDS) reduced as the crystallization temperature increased. A maximum BDS can attain1213.76 kV/cm and a maximum energy storage density can reach up to 4.41 J/cm(3). (C) 2015 Elsevier B.V. All rights reserved.
