Fabrication of porous silica ceramics by gelation-freezing of diatomite slurry

Author(s): , , ,

Using a gelation-freezing method, diatomite-derived porous silica ceramics with high porosities up to 90% were fabricated. Diatomite particles contain large numbers of meso- and micropores, intrinsically reducing the thermal conductivity. In ...
