  • Producing a silicon carbide structure and multidirectional silicon carbide texture
    Patent number: 4325930
    Abstract: The method for producing a silicon carbide structure comprises the stages of immersing the carbon structure into a bath containing 20 to 40% by weight of silicon powder in suspension in a liquid medium containing 10 to 30% by weight of fugitive resin, the remainder being constituted by a resin solvent, and of drying the structure in order to obtain an easy-to-handle carbon structure coated with resin and silicon powder bonded in the resin. The structure is then subjected to a heat treatment to let the silicon react with the carbon and produce a silicon carbide structure.
