【摘要】 固体工业废渣的利用对于变废为宝、减小环境污染程度诸方面具有非常重要的意义 ,利用固体工业废渣制备新型建筑材料是废渣利用的重要发展方向 .为此 ,以锂辉石和铅锌矿尾矿为主要原料 ,添加适宜的其他化工原料 ,采用传统熔体冷却方法而制得几种黄黑色花纹的建筑用材料 .通过X射线衍射分析 (XRD)和利用扫描电子显微镜照片 (SEM)对获得的材料进行了物相和结构研究 ,并与天然石材的理化性能进行了比较 .研究结果表明 :获得的几种材料均是非晶质的 ,结构中含有粒径大约为 0 .2 μm的未完全熔化的SiO2 或Al2 O3 颗粒 ,其理化性能及美学效果与天然石材可比 ,具有开发应用前景 .更多还原

【Abstract】 Some building ornamental materials with yellow black veins and based on the spodumene and the residual slag of Pb Zn mineral have been prepared by conventional melt quenching technology. The physicochemical property and the structure of these materials are investigated by using X ray diffraction and SEM methods and the differences of the properties between the building materials and the natural stone materials are studied. The results show that the materials are non crystal and contain a large number of partial melts SiO 2 or Al 2O 3 particles with 0.2 μm. The properties and the esthetic effects are similar to those of the natural stone materials.更多还原
