Chemical Durability of Waste Fluorescent Glass and Shell–Derived Glass-Ceramics
Tóm tắt
In order to obtain glass-ceramics reinforced by β-wollastonite, pressed specimens prepared by powdered waste fluorescent glass and refuse shell dumped in the seashore were heat-treated at 800°C, 900°C, and 1000°C. Chemical stability of the heat-treated specimens was analyzed by weight changes and by observation of surface morphology and composition, by field-emission scanning electron microscopy and energy dispersive X-ray spectroscopy. Chemical durability of the samples, especially at the glass-matrix area, was decreased with an increase in the heat-treatment temperature from 800°C to 1000°C.
