Preparation method of reaction-bonded silicon carbide
The invention provides a preparation method of reaction-bonded silicon carbide. A monomer, a crosslinking agent dispersant and a raw material are mixed in a ball milling mode, silicon carbide/ carbon black water-based suspensoid of a high solid-phase content and low adhesion is obtained, a green body is formed through a gel injection molding process, and the silicon carbide is obtained after a high-temperature reaction. By means of the preparation method, the silicon carbide in a complex shape can be prepared, sintering time is short, and the preparation method is suitable for preparing large-size silicon carbide products and low in cost.
