摘要 |
A sheet-forming slurry composition is composed of zirconia powder, an organic binder, and a solvent. The zirconia powder contains 2 to 10 mol% of yttria in solid solution form and has a BET specific surface area of up to about 12 m<2>/g and a mean particle size multiplied by the specific surface area of up to 3 mu m.m<2>/g. The composition is formed into a green sheet having improved flexibility, binder removal capability, sinterability, and dimensional stability, which is then fired into a sintered part having improved denseness, gas barrier property, and surface smoothness. |
