Zinc-aluminum spinel coated corundum core-shell structure aggregate as well as preparation method and application thereof
The invention relates to the technical field of corundum aggregates, in particular to a zinc-aluminum spinel coated corundum core-shell structure aggregate and a preparation method thereof. Comprising the following steps: 1, dissolving soluble salt in water, pouring corundum aggregate into the solution, and drying to obtain zinc salt-loaded corundum aggregate; and 2, sintering the corundum aggregate loaded with the zinc salt prepared in the step 1 at a certain temperature to obtain the zinc-aluminum spinel coated corundum core-shell structure aggregate, the zinc-aluminum spinel coated corundum core-shell structure aggregate prepared by the invention has the structural characteristics that the zinc-aluminum spinel forms a compact layer on the corundum shell, the aluminum spinel and corundum are firmly combined, the strength is high, the application range is wide, the erosion resistance is obviously improved when the corundum aggregate with the core-shell structure is used for preparing a refractory castable, and compared with a contrast sample, the erosion resistance is obviously improved. And the erosion depth is reduced by 31.7%, and good erosion resistance is achieved. The preparation method is simple, efficient and worthy of popularization.
本发明涉及刚玉骨料技术领域，具体涉及一种锌铝尖晶石包覆刚玉核壳结构骨料及其制备方法；包括以下步骤：步骤一、将可溶性盐溶于水中，再将刚玉骨料倒入溶液中，烘干得到负载锌盐刚玉骨料；步骤二、将步骤一制得的负载锌盐的刚玉骨料在一定温度下烧结，即可得到锌铝尖晶石包覆刚玉核壳结构骨料；本发明制备锌铝尖晶石包覆刚玉核壳结构骨料，其结构特征为锌铝尖晶石在刚玉外壳形成致密层，铝尖晶石与刚玉结合牢固，强度高，应用范围广，用核壳结构的刚玉骨料制备作耐火浇注料，其抗侵蚀性能明显提高，与对比样相比，侵蚀深度减小了31.7%，具有较好的抗侵蚀性能。且制备方法简单高效，值得推广。
