我们使用金属乙二胺四乙酸 (EDTA) 溶液制造了独特的陶瓷基复合材料 (CMC)，称为纳豆结构氧化物。本研究中的纳豆结构氧化物是微米级氧化物颗粒和具有纳米级纤维微结构的氧化物的组合。通过旋涂带有空心 (Y2O3:Eu3+, SiO2) 颗粒的 Er-EDTA 溶液，然后进行常压烧结，在 Si 基底上制备纳豆结构。我们研究了填料浓度、转速和填料直径对纳豆结构氧化物形成的影响。结果表明，旋涂过程中的旋转离心力是影响纳豆结构氧化物形成的主导因素。
We fabricated unique ceramics matrix composites (CMCs) called natto-structured oxides using metal-ethylenediaminetetraacetic acid (EDTA) solution. The natto-structured oxide in this study is a combination of micron-sized oxide particles and oxide with nanoscale fibrous microstructures. The natto-structures were fabricated on Si substrates by spin-coating Er-EDTA solutions with hollow (Y2O3:Eu3+, SiO2) particles followed by atmospheric sintering. We investigated the effects of filler concentrations, rotation speeds, and filler diameters on the formation of natto-structured oxides. The results indicate that the rotating centrifugal force in the spin coating process is the dominant factor affecting the formation of natto-structured oxides.
