Preparation of silicon carbide foams using polymeric precursor solutions
journal contribution
posted on 2016-09-12, 13:15 authored by Xujin BaoXujin Bao, Muhammad R. Nangrejo, Mohan J. EdirisingheA simple method was developed to produce silicon carbide foams using polysilane
polymeric precursors. Polyurethane foams were immersed in polysilane precursor
solutions to prepare pre-foams. Subsequently, these were heated in nitrogen at different
temperatures in the range of 900±C to 1300±C. The silicon carbide foams produced in this
manner showed well-defined open-cell structures and the struts in the foams were free of
voids. The shrinkage which accompanies pyrolysis of the pre-foams was reduced by
increasing the concentration of the polymeric precursor in the solutions.
