Abstract

A water-filtration membrane made of SiC possesses some excellent properties, but its application is limited by high fabrication cost. In this study, two sets of mullite bonded porous SiC ceramics membranes were prepared at reduced temperature by oxidation bonding method using different processing conditions. Dead-end filtration mode was utilized for the determination of permeability and their efficiency towards removal of turbidity. It was found that all the membranes prepared using different composition, pore formers (graphite, PVC and PMMA) and sintering temperature exhibited high turbidity removal efficiency (> 99%). This study provides an efficient method to prepare porous SiC ceramics with excellent permeability and turbidity removal efficiency, which will be helpful for the design of low cost SiC ceramic filters for water treatment.

工艺参数对莫来石结合SiC膜过滤混浊水的影响

碳化硅滤水膜具有优良的性能，但由于其制作成本高，限制了其应用。在本研究中，采用不同的工艺条件，采用氧化键合法在还原温度下制备了两套莫来石结合的多孔SiC陶瓷膜。终端过滤模式被用来测定渗透性和它们的效率对去除浊度。结果表明，采用不同成分、不同成孔剂(石墨、PVC和PMMA)和不同烧结温度制备的膜均具有较高的除浊效率(> 99%)。本研究提供了一种高效制备多孔碳化硅陶瓷的方法，该方法具有优异的透气性和除浊效率，为低成本碳化硅陶瓷水处理过滤器的设计提供了依据。
