中文摘要：

用磷酸钙引入P元素,仿制出浓淡不一的蓝青色古青瓷釉。利用色度仪、X射线衍射、Fourier红外光谱、X射线光电子能谱和扫描电子显微镜,研究了不同磷酸钙加入量对釉色及显微结构的影响,并分析了呈色机理。结果表明：当磷酸钙加入量分别为2%（质量分数）、4%和6%~8%时,可以得到呈色较佳的天蓝、天青和月白釉。随着磷酸钙含量的增加,生成的Ca9Fe（PO4）7晶体增多,使得Fe2＋和Fe3＋原子比从93.53：6.47降至42.26：57.74;而且分相液滴的尺寸逐渐从46nm增至72nm,从而减弱了结构色。这些因素都使得釉面的亮度值（L＊）和黄蓝值（b＊）增大,釉色逐渐向绿白色发展。

英文摘要：

The celadon glazes with different shades of bhie-green were imitated with the addition of calcium phosphate for introducing the phosphorus （P） to the composition. The samples were characterized by colorimetry, X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and scanning electron microscopy, respectively. The possible coloring mechanism was proposed to explain the variation of glaze colors at different contents of calcium phosphate. The results indicate that the sky-blue, sky-green and moon-white glazes can be imitated at calcium phosphate contents of 2%, 4% and 6%-8%, respectively. The content of calcium iron phosphate （Ca19Fe2（PO4）14） increases, the atomic of Fe2＋to Fe3＋ decreases from 93.53/6.47 to 42.26/57.74, and the size of phase separation droplets increases from 46 to 72 nm with increasing the amount of calcium phosphate, leading to the weakness of structural color in glazes, the increase of the lightness （L^＊） and yellow to blue （b^＊） value and the more green and white of glaze color.
