摘要
采用颗粒稳定泡沫的方法制备出闭孔结构、孔径均匀分布和轻质的氧化钇稳定的氧化锆(YSZ)泡沫陶瓷。研究烧结温度、表面活性剂种类和固含量对泡沫陶瓷骨架组成、孔特性(包括孔隙率、孔径分布和平均孔径)和抗压缩强度的影响规律。结果显示,孔隙率处于45%~85%之间时,YSZ泡沫陶瓷的抗压缩强度与孔隙率之间的关系符合Rice模型;在烧结温度1450℃及固含量为32.50%(体积分数)时,采用异丁烯与马来酸酐共聚物分子和阳离子型表面活性剂十二烷基三甲基氯化铵共稳YSZ湿泡沫制备出的材料综合性能最优,孔隙率为(83.7±0.2)%、平均孔径为(90.1±0.8)μm、抗压缩强度为(45.1±1.3)MPa。在相同孔隙率的情况下,YSZ泡沫陶瓷的抗压缩强度高于大多数已报道的结果。
The light mass YSZ foam ceramic with closed pore structure and uniform pore size distribution were fabricated by the particle-stabilized foams method.Effects of the sintering temperature,surfactant type and solid content of the initial slurries on the strut structure,pore characteristics(porosity,pore size distribution,and average pore size),and compressive strength were investigated.The results show that when the sintering temperature is 1450℃ and solid content is 32.50vol%,the comprehensive performance of YSZ foam ceramic obtained through Isobam molecule and cationic surfactant dodecyl trimethyl ammonium chloride(DTAC)co-stabilized YSZ wet foam is the best,with the porosity of(83.7±0.2)%,mean pore size of(90.1±0.8)μm and compressive strength of(45.1±1.3)MPa.The compressive strength of YSZ foam ceramic in present work is much higher than that of most reported results in the case of the same porosity.
