Fabrication of SiC Porous Ceramics by Foaming Method.

In this work, hierarchically porous SiC ceramics were prepared via the foaming method. Porous ceramics with tunable, uniform, and bimodal pore structures were successfully fabricated in a facile way. The formation mechanisms of the 1st and 2nd modal macropores are the HO foaming process and SiC particle overlap, respectively.
