Abstract
AbstractPorous SiC ceramics are preferable materials for industrial applications such as hot gas filtration and microfiltration, some areas of fine filtration exist where complex structures of ceramic components are required. In this study, a novel method was employed for preparing high‐flux ceramic membranes via selective laser printing. The powder used for laser printing is a laboratory‐prepared polysiloxane powder, which can be pyrolyzed under relatively lower temperatures to obtain SiOC ceramic membranes. From the results of characterization and testing, the obtained ceramic membranes exhibited inimitable pore microstructure, high porosity, and outstanding filtering performance. Laser printing demonstrated good potential to be a strong candidate for the next generation of ceramic membrane fabrication technology.
