Influence of Heat Treatment on Crystallization Properties of Colored RcS Glass-Ceramics
摘要
Abstract
The colored R2O-CaO-SiO2 (RCS, R = Na, K) glass-ceramics were prepared through different heat treatment schedules.The influence of heat treatment on crystallization properties of the colored RCS glass-ceramics was investigated by X-ray diffraction,field emission scanning electron microscopy and UV-Visible spectrophotometer. The results indicate that the main crystalline phase of the glass-ceramics is colunnar xonotlite [Ca6Si6O17 (OH)2] at 700 ℃, and radial canasite (K2Na4Ca5Si12O3OF4) and frankamenite [K3Na3Ca5Si12O3OF3 (OH)1H2O] at 750 and 800 ℃. The color of the glass-ceramics changed from yellow to red and the cut-offwavelength shifted to a longer wavelength with the increase of heat treatment temperature and holding time.关键词
