| 摘 要： | 采用粉煤灰、黄金尾矿为主要原料,添加不同掺量的竹炭,通过干压成型-高温烧成法制得粉煤灰陶瓷砖,分析了竹炭掺量及烧成温度对粉煤灰陶瓷砖的物化性能、物相组成及显微结构的影响规律.结果表明:以粉煤灰、黄金尾矿和竹炭可以制备出显气孔率和强度较高、吸水率较低的粉煤灰陶瓷砖,其物相主要为石英相与莫来石相;在m(竹炭):m(粉煤灰)为5:70,烧成温度为1 250℃时,陶瓷砖具有较好的综合性能,其破坏强度可达600.1 N,吸水率为8.29%,显气孔率为16.02%,达到GB/T 4100—2006附录K中对BⅡ类炻质砖的性能要求,且该材料的比表面积为11.1 m~2/g,具备一定的吸附功能,有望成为一种新型的内墙功能装饰材料.
