SiC Foams Produced by Gel Casting: Synthesis and Characterization

SiC foams were fabricated by gelcasting with a commercially available powder and agar as gelling agent. Ceramic foams processed by gel casting have dense struts and are therefore mechanically stronger than foams produced by the conventional poly‐urethane replica method. First, special attention was...

Description
Summary:SiC foams were fabricated by gelcasting with a commercially available powder and agar as gelling agent. Ceramic foams processed by gel casting have dense struts and are therefore mechanically stronger than foams produced by the conventional poly‐urethane replica method. First, special attention was given to the preparation and characterization of the powder suspension using silicon carbide powders which has been recognized as a high performance material.
