The invention discloses solid waste-based high-strength foamed ceramic and a preparation method thereof. The preparation method comprises the following steps: carrying out wet ball milling on raw materials including silicate tailings, manganese slag, steel slag, potassium feldspar, bentonite and a foaming agent to obtain slurry; drying and sieving the obtained slurry, carrying out compression molding to obtain a ceramic body, and sintering the ceramic body to obtain the high-strength foamed ceramic; the method has the advantages that the process is simple, the sintering energy consumption is low, the industrial production of the ceramic is facilitated, the raw materials are mainly from solid wastes, and the environmental pressure caused by tailings and metallurgical slag is favorably relieved.
本发明公开了一种固废基高强度泡沫陶瓷及其制备方法。将包括硅酸盐尾矿、锰渣、钢渣、钾长石、膨润土及发泡剂在内的原料通过湿式球磨，得到浆料；所得浆料经过干燥、过筛后，压制成型，得到陶瓷坯体，陶瓷坯体经过烧结，即得高强度泡沫陶瓷，该方法且工艺简单，烧结能耗低，有利于陶瓷工业化生产，且原料主要来自固体废弃物，有利于缓解尾矿和冶金渣带来的环境压力。
