Abstract Protein rigid foams based on albumin coreacted with camphor and an aldehyde were converted into silicon
carbide (SiC) foams. This was carried out by putting albumin-derived template foams in contact with
silicon compounds in liquid phase and calcinating the mix obtained at a relatively low temperature of 500°C
to eliminate the protein and leave the SiC foam. The transformation was followed by scanning electron
microscopy (SEM) from the natural albumin foams to the gel obtained by infi ltrating them with tetraethyl
orthosilicate (TEOS) and to the appearance of the SiC foams after calcination. X-ray diffraction (XRD) and
Raman spectra were… More >
