摘　　要：采用甘氨酸燃烧法合成了新型红色YAl1-xCrxO3色料。研究了Cr掺杂量,煅烧温度、保温时间以及矿化剂对YAl1-xCrxO3色料的颜色的影响。结果表明YAl1-xCrxO3色料的色度中的a*值随着Cr掺杂量的增加,煅烧温度的提高和保温时间的延长而增加,色料的红色增加明显。b*值具有与a*值相同的变化规律,其变化的原因是部分Cr3+向Cr4+转变。矿化剂Ca F2具有较好的矿化效果。在1300℃煅烧3 h,能够获得大红色高温YAl0.97Cr0.03O3色料(L*=55.26,a*=26.74,b*=17.44)。A new red YAl1-xCrxO3 pigment was prepared by glycine combustion. The effect of Cr3＋ content, calcination temperature, holding time and mineralizer on the chromaticity of YAl1-xCrxO3 pigment were studied. The results show that the a＊ value of the chromaticity for YAl1-xCrxO3 pigment increases with the increase of Cr^3＋ content, calcination temperature and holding time. Correspondingly, the pigment changes red. The change of the b＊ value is similar to that of the a＊ value, which is the result of the change of Cr^3＋ to Cr^4＋. The mineralizing effect of Ca F2 is better than the others. The bright red YAl0.97Cr0.03O3 pigment can be prepared by calcinating at 1300 ℃ for 3 h with L＊=55.26, a＊=26.74 and b＊=17.44.
