cellular porous ceramic
The process of obtaining silicon oxycarbide (SiOC) ceramic foams is simple, economical and versatile, and consists of co-blowing a silicone resin with or without polyurethane precursors (polyols and isocyanates). The green porous bodies are converted into a SiOC ceramic foam by pyrolysis in nitrogen, and both open and closed cell macro cellular foams can be produced. This makes it possible to produce porous ceramics in any shape or design according to specification; rods, tubes, and thin plates are typically manufactured.
Porous ceramics are used in gas absorption, chromatography, vacuum holding plates and filtration for heavy metal ions in water.
