Abstract
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.
Claims4
A method for producing a siliconized carbon foam comprising the steps of:
- blending a predetermined amount of comminuted coal with a predetermined amount of particulate silicone resin to form a blended mixture;
- heating the blended mixture to a temperature sufficient to form a siliconized carbon foam wherein at least a portion of the silicon from the particulate silicone resin reacts with carbon to form silicon carbide in at least a portion of the siliconized carbon foam.
Dependencies are inferred from the claim text.
