以硅铝系固体废弃物为原料合成Sialon环境材料,不仅为固体废弃物的深度利用提供了一条新的思路,而且为Sialon材料的廉价合成提供了一条新的绿色工艺.简单介绍了冶金-高炉钙硅铝(钛)废渣、大宗能源系富含硅铝矸石尾矿、电厂铝硅铁灰渣、高硅多杂江河淤泥沙、稀土及贵金属伴生硅酸盐选矿后尾矿等硅铝系固体废弃物的概况,详细阐述了硅铝系固体废弃物合成Sialon材料的国内外发展现状,并对其发展前景进行了展望.
The synthesis of Sialon ecomaterials drived from solid waste of containing silican and aluminum provides a new method to utilize the solid waste high-technically, and a new green process for low-cost preparation of Sialon material. Blast furnace slag, coal gangue, fly ashes, sediment, tailings, etc, are briefly introduced. It could be designed to synthesize α-Sialon, β-Sialon, O'-Sialon, etc, composite materials based on the chemical composition of these solid waste. The present development and prospects of Sialon ecomaterials drived from solid waste are reviewed and predicted.
