IMPREGNATED CERAMIC FOAM MADE OF RECRYSTALLIZED SILICON CARBIDE

摘要

Porous ceramic part comprising a porous ceramic foam having a total porosity of between 50 and 92 % and an intergranular porosity of at least 5 %, walls of at least some of the cells of the ceramic foam being at least partly covered with an impregnation material. The invention relates in particular to a recrystallized silicon carbide foam impregnated with silicon.
