Abstract

Manufacturing ceramic green structures using starch consolidation casting is an established process that is simple, non-hazard, and low-cost. In this study, starch consolidation casting is used to prepare ceramics based on submicron monoclinic zirconia with additions of alumina and magnesia. Scanning electron microscopy results indicate that the size of pores decreased and the morphological irregularity increased when the tapioca starch content increased. The sample with 30 wt.% tapioca starch in a 55 wt.% slurry concentration had the highest estimated apparent porosity (around 56%), whereas the sample with 10 wt.% in a 68 wt.% suspension concentration had the lowest (about 35%).

氧化锆-氧化铝生物陶瓷的孔隙率和孔隙形态特征

使用淀粉固结浇注法制造绿色陶瓷结构是一种成熟的工艺，具有简单、无害和成本低的特点。本研究采用淀粉固结浇注法制备基于亚微米单斜氧化锆并添加氧化铝和氧化镁的陶瓷。扫描电子显微镜结果表明，当木薯淀粉含量增加时，孔隙尺寸减小，形态不规则性增加。在浓度为 55 wt.% 的泥浆中，木薯淀粉含量为 30 wt.% 的样品的表观孔隙率最高（约 56%），而在浓度为 68 wt.% 的悬浮液中，木薯淀粉含量为 10 wt.% 的样品的表观孔隙率最低（约 35%）。
