A method for producing a siliconized carbon foam with regions of silicon carbide directly from comminuted coal and particulate silicone resin precursor is described. The process includes blending a comminuted coal and particulate silicone resin and heating the blended mixture to form a siliconized carbon foam and then further heating to form regions of silicon carbide.

Carbon foam based silicon carbide

A method for producing silicon carbide directly from comminuted coal and a silicon precursor is described. The process includes coating comminuted coal with a silicon precursor and heating the silicon precursor coated comminuted coal to initially form polymerized preceramic silicon-carbon foam and then further heating to form silicon carbide foam.

Coal based silicon carbide foam

Producing silicon carbide carbon foam is described. The process includes filling the pores of a carbon foam with a polysiloxane resin and heating the impregnated carbon foam to high temperatures to convert the silicon in the polysiloxane resin to silicon carbon within the carbon foam.
