采用低毒单体N,N-二甲基丙烯酰胺(DMAA)制备了氧化锆增韧氧化铝(ZrO2/Al2 O3,ZTA)陶瓷,氧化铝与氧化锆的质量比为3∶1,浆料的固相体积分数为50 vol%.讨论了不同干燥方式对干燥速率以及坯体性能的影响,研究了不同成型温度对坯体性能的影响.通过研究发现,在湿热烘箱中干燥的坯体强度最高,成型温度应控制在65℃附近.通过对不同单体含量的坯体烧结后陶瓷性能的对比,发现单体的加入量为10wt%左右较好,通过与干压成型陶瓷性能的对比,发现注凝成型得到的陶瓷强度和韧性分别提高了42.2%和23.5%,达到640 MPa和6.3MPa.m1/2,通过扫描电镜图片分析发现,注凝成型制得的陶瓷结构更均匀.
