摘要

本文以孔径在7-10 ppi范围内的聚苯乙烯-聚氨酯泡沫为原料，采用复制法制备了3和8 mol%钇稳定氧化锆(3YSZ和8YSZ)的陶瓷泡沫。为了增厚支柱，防止微结构缺陷，在预熔泡沫上进行了第二次涂层。对制备的泡沫陶瓷进行了结构和热力学表征。复涂3YSZ的样品呈现出最高的相对密度()，这有助于更好的力学和热行为。

Processing and Characterization of Yttria-Stabilized Zirconia Foams for High-Temperature Applications

In this work ceramic foams of 3 and 8 mol% yttria-stabilized zirconia (3YSZ and 8YSZ) were manufactured by the replication method using polystyrene-polyurethane foams with pore sizes in the 7–10 ppi range. A second coating was carried out on presintered foams in order to thicken struts and hinder microstructural defects. The produced ceramic foams were structurally and thermomechanically characterized. Samples recoated with 3YSZ presented the highest relative densities () which contributed to a better mechanical and thermal behavior.
