Method for preparing ceramic composite microwave absorbing material from red mud
The invention relates to a method for preparing a ceramic composite microwave absorbing material from red mud, belongs to the technical field of microwave absorbing material preparation, and solves the problem of pollution caused by discharge and accumulation of solid waste red mud. According to the solution scheme, the method comprises the following steps: firstly, carrying out filter pressing and dispersion treatment on red mud, and then crushing and ball-milling a reducing agent; and slowly adding red mud briquettes with a certain water content and reducing agent powder into a mixer, uniformly conducting mixing to form red mud-based composite pellets, drying the composite pellets, and carrying out carbon thermal reduction to obtain the Fe3O4, Fe or FeC-loaded ceramic composite microwave absorbing material. The solid waste red mud is used as the raw material to prepare the ceramic composite wave-absorbing material, so that the effective recovery of the red mud is realized, the cost of the microwave absorbing material can be reduced, and the method is suitable for large-scale industrial production.
本发明涉及一种利用赤泥制备陶瓷复合微波吸收材料的方法，属于微波吸收材料制备技术领域，解决因固废赤泥排放、堆积引起的污染问题，解决方案为：首先对赤泥浆进行压滤、分散处理，然后对还原剂进行破碎、球磨加工，混合机中缓慢加入一定含水量的赤泥团料和还原剂粉体，混合均匀后形成赤泥基复合小球，接着将复合小球经干燥、碳热还原即可获得负载Fe3O4、Fe或者FeC的陶瓷复合微波吸收材料。本发明以固废赤泥为原料制备陶瓷复合吸波材料，不仅实现了赤泥的有效回收，而且可以降低微波吸收材料的成本，适合于规模化工业生产。
