Abstract

A porous silicon carbide (SiC) ceramic filter was prepared at 1000°C using waste red mud (RM), SiC, pore‐forming agent, and catalyst. The influence of sintering temperature, RM content, and pore former on the mechanical performance and the porosity of porous ceramics were investigated, and based on the result optimal processing parameters were selected. The air and water permeability tests were carried out at room temperature. The stability of the ceramic filter under thermal shock and chemical treatment was investigated and corroded samples were characterized. The ceramic was prepared using optimized processing parameters obtained with a flexural strength of 65.36 MPa at a porosity of 30.15 vol.% and demonstrated good performance in terms of pure water flux, oil, and turbidity removal efficiency from industrial wastewater. The filtration and permeation results indicated that the SiC filter prepared in this study is suitable for various applications, particularly in the remediation of oil‐polluted water.

通过回收利用废弃赤泥制作碳化硅陶瓷过滤介质并确定其特性

利用废弃赤泥（RM）、碳化硅、成孔剂和催化剂在 1000°C 下制备了多孔碳化硅（SiC）陶瓷过滤器。研究了烧结温度、RM 含量和成孔剂对多孔陶瓷机械性能和孔隙率的影响，并根据结果选择了最佳加工参数。透气性和透水性测试在室温下进行。研究了陶瓷过滤器在热冲击和化学处理下的稳定性，并对腐蚀样品进行了表征。采用优化的加工参数制备的陶瓷在孔隙率为 30.15 vol.% 时的抗折强度为 65.36 MPa，在工业废水的纯水通量、油和浊度去除效率方面表现出良好的性能。过滤和渗透结果表明，本研究制备的碳化硅过滤器适用于各种应用，尤其是油污染水的修复。
