| Abstract: | ZrB2–SiC green ceramics were fabricated by aqueous gelcasting based on single AM‐MBAM, single Na‐alginate, and double gel network system. ZrB2–SiC ceramics obtained by aqueous gelcasting based on AM‐MBAM and Na‐alginate double gel network had a dramatically highest green strength of 98.6 ± 5.1 MPa, which was 103% and 61% higher than that of ZrB2–SiC ceramics based on single AM‐MBAM system and Na‐alginate system, respectively. A “scratch test” was conducted to evaluate the green machinability of as‐prepared ZrB2–SiC ceramics. The ZrB2–SiC ceramics based on this double gel network was found to have the best green machinability. |
