摘　　要：以Zn(NO3)2·6H2O、Co(NO3)2·6H2O、Al(NO3)3·9H2O和C12H22O11为原料,采用溶液燃烧法合成ZnxCo1-xAl2O4(0≤x≤1)尖晶石型陶瓷色料。采用X射线衍射(XRD)、扫描电子显微镜(SEM)和色度分析仪等检测方法对Zn2+的掺杂量和热处理温度对合成粉体的物相组成、微观形貌和呈色性能的影响规律进行了表征。结果表明:在Zn2+掺杂量x=0.2、前驱体溶液中(Zn2++Co2+)浓度为0.3 mol/L、点燃温度400℃、后续热处理温度1200℃和保温时间30 min条件下,合成色料的蓝度值(-b*)达47.03的最大值,其平均晶粒尺寸为120 nm。ZnxCo1-xAl2O4（0≤x≤1） ceramic pigment were prepared by the solution combustion method using Zn（NO3）2·6H2O,Co（NO3）2·6H2O,Al（ NO3）3·9H2O and C12H22O11 as starting materials.The effects of Zn2 ＋doping contents and heat treatment temperature on the phase composition,microstructure and color performance of the prepared ceramic powders were investigated by XRD,SEM and color analyzer. The results show that the chromatic value（- b＊） arrived at maximum value（47.03） on conditions that Zn2 ＋doping content x = 0. 2,precursor solution concentration（Zn2 ＋＋ Co2 ＋） 0.3mol /L,igniting temperature 400 ℃ and subsequent heat-treatment system 1200 ℃ for 30 min,and the average grain size of the above as-synthesized ceramic pigment is 120 nm.
