本文提出并发展了一种陶瓷薄板微图形化工艺。具有微图案的薄片已经被期望改善固体氧化物燃料电池的性能。作者将压印技术与粉末冶金技术相结合，提出了一种新的复合工艺--微粉压印工艺。在该工艺中，陶瓷粉末和聚合物粘结剂材料通过研磨机与纯水混合。在干燥浆料中的水之后，获得薄的复合片。随后，使用精细图案化模具在加热下压制片材以在片材上转录微图案。最后，将压印的片材加热以除去聚合物粘合剂并进行烧结。作为该方法的进一步改进，在压印过程中将复合片堆叠在纯聚合物片上，以在烧结样品的两侧上转录微图案。该技术可用于改进固体氧化物燃料电池。
A micro patterning process for thin ceramic sheets is proposed and developed in this paper. Thin sheets with a micro pattern have been expected to improve performance of solid oxide fuel cell. The authors focused on imprinting and powder metallurgy processes, and have developed the combined process, which has been named micro powder imprinting process. In this process, ceramic powder and polymer binder materials are mixed with pure water by milling machine. After drying out the water from the slurry, a thin compound sheet was obtained. Subsequently, the sheet was pressed using a fine patterned mold with heating to transcribe a micro pattern on the sheet. Finally, the imprinted sheet was heated for removing the polymer binder and for sintering. As further improvement of the process, a compound sheet was stacked on a pure polymer sheet during the imprint process to transcribe a micro pattern on the both sides of the sintered sample. The technique is useful for improved solid oxide fuel cell.
