摘要：

Coatings of 8.8-mol%-yttria-doped zirconia were fabricated using a transparent and spinnable sol prepared by hydrolysis of zirconium alkoxide with hydrogen peroxide and nitric acid. The sol gave a crack-free coating film consisting of fine grains. The crystalline phase was cubic after heating at 1000-degrees and 1200-degrees-C and cubic and tetragonal at 1350-degrees-C, with the coating being highly oriented in the (111) plane, especially at 1000-degrees-C. Activation energy of the coating films was higher than that of the bulk. Transmittance through a film thickness of about 0.3 mum on each side was 75%.
