摘要

为了研究特定陶瓷材料的结构和性能,采用模压法制备了常用的陶瓷建筑材料赤泥、钢渣和滑石。采用差示扫描量热法、x射线衍射法和扫描电镜研究了颗粒大小和成分对陶瓷材料性能的影响。结果表明,其主要晶相为透辉石和钙长石。当烧结温度为1170℃左右,原料粉末粒度小于74 μm,赤泥含量为60-70%,钢渣含量为20-30%,滑石粉含量为10%时,陶瓷的力学性能最佳。研究结果对钢渣和赤泥的大规模资源化利用具有一定的指导意义。

A Novel Fabrication Approach for Ceramic Tiles from Red Mud and Steel Slag

A Novel Fabrication Approach for Ceramic Tiles from Red Mud and Steel Slag

In order to investigate the structure and performance of specific ceramic materials, red mud, steel slag, and talc, which are commonly used as ceramic building materials, were fabricated by molding. The influences of particle size and composition on the properties of the ceramic materials were studied by differential scanning calorimetry, X-ray diffraction and scanning electron microscopy. The results indicate that the main crystalline phases were diopside and anorthite. The ceramics possessed the best mechanical properties when sintered at about 1170°C, the particle size of the raw material powders was less than 74 μm, and the ceramic composition comprised 60–70% red mud, 20–30% steel slag, and 10% talc. The results of this work are useful for recycling of steel slag and red mud on a large scale.
