摘要：Nanostructured glass-ceramic glazes with smooth and glossy surface textures were synthesized from coal fly ash and blast furnace slag by a simple sintering process. Sintering and crystallization behaviours of the glass-ceramic glaze obtained were investigated by x-ray fluorescence (XRF), differential thermal analysis and thermogravimetry (DTA/TG), powder x-ray diffraction (XRD) and scanning electron microscope (S EM) equipped with energy dispersive x-ray detector (EDX). The results revealed that the amount of main crystalline phases changed with varying sintering temperatures and approached saturation at 1160 degrees C. The main crystalline phase of the glass-ceramic glazes sintered at 1160 degrees C was anorthite, and the anorthite phase content increased with increasing holding times at the crystallization temperature of 956 degrees C. The glass-ceramic glaze obtained had a high Vickers hardness of 9.69 GPa, negligible water absorption, good adherence to the ceramic support, a thermal expansion coefficient of 7.6x10(-6) degrees C(-1) and admirable suitability to industrial rapid sintering. The good distribution of spherical anorthite crystals with a uniform size of about 250 nm was responsible for the excellent properties. A possible crystallization mechanism for this glass-ceramic glaze is proposed.
