摘要
结合流延法和凝胶法的优点 ,形成了水溶液丙烯酰胺体系的凝胶 -流延成型方法。以固相含量为 5 4vol%的 YSZ悬浮体为浆料 ,利用此方法制备了厚度小、致密度高、气孔少的固体电解质 Zr O2 薄片 ,并从粉体特性、分散剂和 p H值对悬浮体性能的影响、素坯及烧结体密度等多角度探讨了工艺的特点。研究表明与干压法、流延法相比 ,用凝胶 -流延成型的薄片致密度高 ,气孔少 ,适合制备固体电解质
A new method of tape casting was modified with the advantages of gelation A thin solid electrolyte film of yttria stabilized zirconia with high density, less porosity was fabricated by this method with 54vol% solid content slurry The character of the process was discussed based on the aspects of powder, influence of disperant and pH on slurry, density of green body and sintered materials The experiments show that compared with pressing and tape casting, geltape casting can fabricate thin film with high density and homogenous structure The method is suitable for preparing thin electrolyte film of yttria stabilized zirconia
