摘要

胶带浇铸是一种制造可扩展陶瓷片的灵活技术。本研究利用水基带浇铸技术制造了 La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF6428) 带。选择高分子量增塑剂聚乙二醇 4000 来平衡柔韧性和机械强度。通过调整增塑剂与粘合剂的比率（R 值）以及在干燥过程中增加相对湿度，可获得无裂纹、无瑕疵的 330 µm 绿色胶带。均匀的聚合物基质也提高了均匀性和一致性。开发出了一种适用的悬浮液配方，可用于水基 LSCF 胶带的连续生产。

Influence of drying conditions and plasticizer-to-binder ratio on the water-based tape casting of La0.6Sr0.4Co0.2Fe0.8O3−δ

Tape casting is a flexible technique for manufacturing scalable ceramic sheets. This study fabricated La_0.6Sr_0.4Co_0.2Fe_0.8O₃₋_δ (LSCF6428) tapes using water-based tape casting. A high molecular weight plasticizer, polyethylene glycol 4000, was chosen to balance flexibility and mechanical strength. Adjusting the plasticizer-to-binder ratio (R-value) and increasing relative humidity during drying led to crack-free and flawless green tapes of 330 µm. The uniform polymer matrix improved homogeneity and consistency as well. An applicable suspension formulation was developed for the water-based fabrication of LSCF tapes for continuous production.
