Processing Characterization and Modeling of Room
A novel method was developed to produce ceramic foams from a silicone precursor which was foamed and vulcanized at room temperature. Silicone foams were prepared by platinum‐catalyzed cross‐linking and dehydrogenation of reactive polysiloxanes. Silicone foams were converted to ceramic foams after being pyrolyzed at 1200°C in argon.
