(一)试验方法 由上海工业大学提供纯ZrO_2和Y-PSZ(氧化钇稳定的部分稳定氧化锆)粉末,平均粒径为0.05～0.1μm。在医用压片机上将混有成型剂的粉末压制成19×14×2mm的薄片,经脱除成型剂后,在箱式硅化钼炉中于1450～1500℃保温2h烧结成约13.5×10 ×1.5mm的瓷片作为X射线衍射试样。常温X射线衍射在菲利浦APD-10全自动X射线衍射仪上进行。高、低温X射线衍射在日本理学
(A) Test Method Pure ZrO 2 and Y-PSZ (yttria-stabilized partially stabilized zirconia) powders are provided by Shanghai University of Technology with an average particle size of 0.05-0.1 μm. In the medical tabletting machine will be mixed with a molding agent powder pressed into a 19 × 14 × 2mm sheet, after removing the molding agent, in a box-type molybdenum silicide furnace 1450 ~ 1500 ℃ incubated 2h sintered to about 13.5 × 10 × 1.5mm ceramic tiles as X-ray diffraction samples. Normal temperature X-ray diffraction was performed on a Philips APD-10 automatic X-ray diffractometer. High and low temperature X-ray diffraction in Japanese science
