Low-cost porous ceramic filters for potential microfiltration and ultrafiltration applications

J.-H. Ha*, J. Lee, I.-H. Song, Korea Institute of Materials Science (KIMS), Korea

Recently porous ceramic filters have become a subject of special interest due to their outstanding thermal and chemical stability. To alleviate the manufacturing cost issues of porous ceramic filters, recent research is focused on the utilization of low cost raw materials.

In this study, we introduced porous ceramic filters prepared from low cost raw materials such as diatomite, kaolin, pyrophyllite, and silicon carbide. And we report the results of our efforts to determine whether we could prepare a low-cost ceramic filter that could control the average pore size, the largest pore size, the flexural strength and the air/water permeability effectively. The pore characteristics of the specimens were studied by scanning electron micrography, mercury porosimetry, capillary flow porosimetry, and a dead-end microfiltration system with particle counters...
