Foamed ceramic as well as preparation method and application thereof
The invention provides foamed ceramic as well as a preparation method and application thereof. The interior of the foamed ceramic is of a porous structure, pores are mutually independent and not communicated, and the surface of the foamed ceramic is of a pore-free continuous compact structure; the foamed ceramic is mainly prepared from the following raw materials in parts by weight: 60-75 parts of lithium tailings, 20-35 parts of lithium slag and 3-7 parts of bentonite. The foamed ceramic further comprises a composite foaming agent, and the composite foaming agent accounts for 0.1-3 wt% of the total weight of the lithium tailings, the lithium slag and the bentonite. The lithium tailings and the lithium slag are synergistically absorbed, and the closed-cell foamed ceramic with the ultralow water absorption rate is successfully developed and produced through raw material homogenization treatment, formula design, scheme optimization and high-temperature firing.
本发明提供一种泡沫陶瓷、其制备方法与应用,所述泡沫陶瓷的内部为多孔结构,各孔彼此独立不连通,而表面为无孔隙的连续致密结构;所述泡沫陶瓷主要由以下重量份数的原料制备得到:60~75份锂尾矿、20~35份锂渣、3~7份膨润土;所述泡沫陶瓷的原料还包括复合发泡剂,所述复合发泡剂占锂尾矿、锂渣和膨润土的总重量的0.1~3wt%。本发明将锂尾矿、锂渣协同消纳,通过原料均化处理,配方设计,优化方案,高温烧成,成功研制生产出超低吸水率闭孔泡沫陶瓷。
