摘要
以城市生活垃圾焚烧飞灰、废屏玻璃、化学辅助试剂为原料,采用熔融法制备了复合晶相的微晶玻璃,采用DSC、XRD、SEM等研究了晶化温度(940℃-1060℃)对结晶过程和晶相结构变化的影响,测试了微晶玻璃样品的体积密度、吸水率、抗弯强度、显微硬度等性能。结果表明:晶化温度为1030℃时,微晶玻璃的体积密度、抗弯强度、显微硬度最大,分别为2.81 g·cm^(-3),83.78 MPa和7.4 GPa,吸水率最小为0.10%。
Glass-ceramics with the pyroxene,forsterite and mullite as the crystalline phases were prepared using fly ash,waste panel glass and chemical reagents by melting method.Effect of crystallization temperature(940°C-1060°C)on the crystal performance and microstructure of glass-ceramic samples was analyzed by means of differential scanning calorimetry(DSC),X-ray diffraction(XRD),and scanning electron microscope(SEM).The properties of density,water absorption,flexural strength and micro hardness were also measured.The results showed that the glass-ceramics with the highest bulk density(2.81 g/cm^3),highest flexural strength(83.78 MPa),highest micro hardness(7.4 GPa)and the minimum water absorption(0.10%)were obtained by crystallizing at 1030°C.
