| 摘 要： | 垃圾焚烧飞灰电弧炉熔渣经核化、晶化两步处理制备微晶玻璃,采用差热分析法研究了基础玻璃的晶化行为,考察了晶化时间对微晶玻璃微观结构及理化特性的影响。结果表明:基础玻璃的晶化指数为1.48,以表面析晶为主,其最佳热处理制度为:核化温度679℃、核化时间1.5h、晶化温度985℃、晶化时间1.5h。微晶玻璃的主晶相为透辉石Ca(Mg,Al)(Si,Al)_2O_6和少量普通辉石Ca(Mg,Fe,Al)-(Si,Al)_2O_6,在最佳热处理条件下制得的微晶玻璃具有较高的抗弯强度、硬度、韧性及耐酸碱性等性能,有替代天然建材的潜力。

| Abstract: | Glass-ceramics by nucleating and crystallization of the molten slag obtained from incinerator fly ash using electric arc furnace treatment was produced.The crystallization behaviour of parent glass was examined on the basis of differential thermal analysis(DTA) results.The effects of crystallization time on the microstructure and the properties of glass-ceramics were studied.The experimental results showed that Avrami exponent for parent glass is 1.48 which indicated that the surface crystallization is domi... |
