Porous calcium silicate ceramic and ultra-fast preparation method thereof
The invention belongs to the technical field of inorganic ceramic materials, and particularly relates to porous calcium silicate ceramic and an ultra-fast preparation method thereof. The method aims to solve the problems of complex preparation process, high energy consumption and long time of the calcium silicate porous ceramic. The preparation method of the porous calcium silicate ceramic comprises the following steps: taking an industrial by-product, namely active calcium silicate, generated after aluminum oxide is extracted from high-alumina fly ash as a raw material, adding starch as a binder, uniformly mixing, and pressing into a ceramic-based biscuit by using a mold; and sintering the to-be-sintered ceramic-based biscuit through an ultra-fast sintering technology to obtain the porous structure ceramic.
本发明属于无机陶瓷材料技术领域，尤其涉及一种多孔硅酸钙陶瓷及其超快速制备方法。本方法旨在解决硅酸钙多孔陶瓷制备工艺复杂，能耗高及时间长的问题。所述多孔硅酸钙陶瓷的制备方法包括以下步骤：将高铝粉煤灰提取氧化铝后产生的工业副产物一活性硅酸钙作为原料，加入淀粉作为粘结剂，混合均匀，使用模具压制成陶瓷基素坯；将待烧结的陶瓷基素坯通过超快速烧结技术进行烧结，得到多孔结构陶瓷。
