采用正硅酸乙酯为碳源和硅源,四氯化锆为锆源,LiF为矿化剂,通过非水解溶胶-凝胶法(NHSG)制备了硅酸锆包裹炭黑(C@ZrSiO4)色料.通过XRD和SEM研究了前驱体和矿化剂浓度对硅酸锆合成及显微形貌的影响,同时采用CIE-L*a+b+色度仪考察了该色料的色度.实验结果表明,正硅酸乙酯中的乙氧基原位炭化成细小的碳粒作为发色基团,同时与氯化锆通过非水解溶胶-凝胶反应生成硅酸锆均匀包裹于炭黑颗粒表面.随着前驱体浓度的增大原位碳含量增加,C@ZrSiO4色料黑度提高;前驱体浓度高于3mol·L-1时样品颗粒团聚严重,同时过厚的包裹层不利于色料发色.经氮气气氛900℃热处理2h,空气气氛800℃热处理2h后制备出的C@ZrSiO4黑色包裹色料具有良好的色度值,L* =44.54,a*=0.82,b*=2.84,施于透明基础釉中经1200℃煅烧仍能保持优异的呈色能力.
