Ceramic filters
Web link 1
This site provides a comprehensive look at why ceramic filters need to be developed, the important role they play in molten metal filtering and their role in relation to fuels.
It explores both the porous foam-like structure with interconnected pores that vary in direction or cross section, and the extruded porous cellular or honeycomb structure with cells of various shapes (square or triangular) and constant cross section.
The site examines the limitations to design of such filters and the manufacturing processes adopted.
