Effects of Mass Ratio of CaO to Al2O3 on Structure and Properties of Slag Glass-Ceramics
摘 要
以白云鄂博二次选后尾矿和粉煤灰为主要原料, 采用熔融法制备了矿渣微晶玻璃, 利用DTA、XRD、SEM等测试手段研究了原料中wCaO/wAl2O3值对微晶玻璃结构及性能的影响。结果表明: 基础玻璃的晶化温度随着wCaO/wAl2O3值的减小有升高的趋势; 随着wCaO/wAl2O3值的降低, 微晶玻璃的抗弯强度先增后降, 钙长石相的出现导致微晶玻璃的抗弯性能降低; 当wCaO/wAl2O3值为4.5时, 微晶玻璃的综合性能最佳, 抗弯强度为164.9 MPa, 密度为2.98 g·cm-3, 耐酸度为92%, 耐碱度为99%。
Abstract
Taking the Baiyunebo tailing and fly ash as main raw material, the slag glass-ceramics were prepared by melting method. The effects of mass ratio of CaO to Al2O3 in raw materials on the structure and properties of the glass-ceramics were studued by differential thermal analysis (DTA), X-ray diffraction (XRD), scanning electron microscopy (SEM). The results show that the crystallization temperature of the base glass increased with the decrease of mass ratio of CaO to Al2O3. It could be found that the bending strength of the glass-ceramics first increased and then decreased with the decrease of mass ratio of CaO to Al2O3 and the bending property decreased because of the appearance of anorthite. The glass-ceramics had the best comprehensive properties when the mass ratio of CaO to Al2O3 was 4.5, the bending strength of the glass-ceramics was 164.9 MPa, the density was 2.98 g·cm-3, the acid-resistance was 92% and the alkali-resistance was 99%.
