摘　　要：通过把金黄色云母珠光颜料分散在四种陶瓷熔块釉中,研究了云母珠光颜料在建筑陶瓷釉面砖装饰的呈色和光泽效果,利用XRD衍射仪、测色仪等仪器对所制备的仿金陶瓷釉面进行了性能表征。结果表明:当金黄色锂云母珠光颜料为15wt%时,被装饰的釉面随着温度升高到900℃快烧时,都呈现较强的金色光泽;但随着温度的继续升高或烧成周期的延长,都会导致金色光泽减弱,通过XRD分析表明,这主要是由于锐钛矿向金红相转化和锂云母相向钾长石相转化所致。该颜料的研制有望替代昂贵的金属装饰。In this work,special-effect pigments with gold luster for the decoration of ceramic tiles was developed and then their color and luster on ceramic tiles were observed by having them added to four ceramic coatings and then fired in a wide range of temperatures.Their technological behavior was assessed by determining their phase composition（XRD） and their colorimetric parameters.Results indicate that the samples with the addition of 15wt% mica titania pigments,are increasingly better with gold luster in ceramic glaze with the firing temperature going up to 900 C,and deterioration of their optical properties is due to anatase-to-rutile and muscovite-to-feldspar transformations occurring at a higher temperature or after a longer firing cycle.XRD patterns show these pigments can replace expensive precious metals lustres.
