中文摘要：

以CeO2,Fe2O3,Er2O3为着色剂,制备不同颜色的Al2O3渗透玻璃,并渗透入预烧结的多孔Al2O3坯体,用分光光度计测量渗透后Al2O3-玻璃复合材料的反射光谱和颜色参数,考察了着色剂含量对材料颜色的影响.结果表明,CeO2能赋予材料黄色品,对降低明度和增加红色品作用较弱;Fe2O3能赋予材料红色品并显著降低明度;Er2O3能增加红色品,对明度和黄色品影响较小.得到的色度范围为L^＊（明度）73.5～91.6,a^＊（红绿色品）-2.84～4.11,b^＊（黄蓝色品）15.6～25.3.对实验数据拟合得到配色模型,以市售核瓷产品为目标进行配色,色差均小于1.5,满足颜色匹配的要求.

英文摘要：

CeO2, Fe2O3 and Er2O3 were used as colorants in alumina infiltration glass system. The pigmented infiltration glass was prepared and then infiltrated in pre-sintered porous alumina, the reflecting spectra and color parameters of glass-infiltrated alumina composite were measured by spectrophotometer, and the effects of different colorants content on the color properties were investigated. Experimental results showed that CeO2 could endow the composite with yellow value, Fe2O3 could endow the composite with red value and decrease the lightness effectively, and Er2O3 could obviously increase the red value, but had slight effect on the lightness and yellow value. The chroma ranges were L^＊（lightless） in 73.5-91.6, a^＊（red-green value） in -2.84-4.11, b^＊（yellow-blue value） in 15.6-25.3. Following experiments showed that the chromaticity differences were not more than 1.5, which were considered to match.
