Method for preparing mullite-corundum composite ceramic from bauxite clinker waste
The invention relates to a method for preparing mullite-corundum composite ceramic from bauxite clinker waste, and belongs to the technical field of solid waste high-value material utilization. According to the invention, bauxite clinker waste and lithium chinastone are adopted as main raw materials, and the mullite-corundum composite ceramic material is obtained by crushing, grading, burdening, mixing, drying, molding and sintering processes. By adding the lithium chinastone, the sintering temperature can be reduced, the density and mechanical property of the mullite-corundum multiphase material can be improved, and technical support can be provided for high-value utilization of the bauxite clinker waste.
本发明涉及到一种利用铝矾土熟料废料制备莫来石‑刚玉质复相陶瓷的方法，属于固废高值材料化利用技术领域。本发明采用铝矾土熟料废料和锂瓷石为主要原料，经过破碎、分级、配料、混料、干燥、成型、烧结工艺进行处理得到的莫来石‑刚玉质复相陶瓷材料。锂瓷石的加入可以降低烧结温度，提高莫来石‑刚玉质复相材料的致密度和力学性能，可为铝矾土熟料废料高值化利用提供技术支撑。
