以蛇纹石为原料经浓酸处理 ,其滤液用于制备轻质氧化镁 ,其残渣主要成分是二氧化硅 ,对残渣进一步超细粉磨加工制成人造硅灰。利用近代测试技术对人造硅灰的形貌、晶相、物相及孔结构和微结构形成过程进行研究 ,测试结果表明 ,人造硅灰是一种非晶态、隐晶质物质 ,具有较大的内比表面积的多孔体 ,具有较高的火山灰活性 ,是一种较为理想的替代硅灰材料。 Serpentine as raw material by concentrated acid treatment, the filtrate for the preparation of light magnesium oxide, the main component of the residue is silica, the residue was further ultrafine grinding made of artificial silica fume. The modern test technology was used to study the morphology, crystal phase, phase, pore structure and microstructure formation of artificial silica fume. The test results show that artificial silica fume is an amorphous and implicit crystal material with a large Of the internal surface area of ​​the porous body, with high pozzolanic activity, is a more ideal alternative silica fume material.
