摘　　要：以核桃壳粉、八水氧氯化锆(ZrOCl2·8 H2O)和正硅酸乙酯(TEOS)等为原料,采用溶胶-沉淀法制备了硅酸锆包裹炭黑(C@ZrSiO_(4))黑色色料。通过TG-DSC、FT-IR、XRD、SEM、TEM等对试样的热效应、化学结构、物相组成和微观结构进行了表征,研究了不同热处理温度、核桃壳粉/硅酸锆质量比(理论合成,下同)等对色料组成和色度的影响规律。结果表明,当热处理温度为1100℃、核桃壳粉/硅酸锆质量比为1∶3时,合成的C@ZrSiO_(4)色料发色性能最佳,L^(*)=31.3、a^(*)=+1.4和b^(*)=+1.3;在透明釉中外加5%(质量分数)C@ZrSiO_(4)色料,经1200℃烧成所制备的黑釉具有较好的呈色效果,其色度值L^(*)=41.2、a^(*)=+1.2和b^(*)=+1.7。Zirconium silicate encapsulated carbon(C@ZrSiO_(4))black pigment was prepared by sol-precipitation method,using walnut shell powder,zirconium oxychloride(ZrOCl2·8H2O)and ethyl silicate(TEOS),etc.as raw materials.The heat effect,chemical structure,phase composition and microstructure of samples were investigated by TG-DSC,FT-IR,XRD,SEM and TEM.The effects of different heat treatment temperatures and mass ratios of walnut shell powder/ZrSiO_(4)(theoretical synthesis,the same below)on the phase composition and chromaticity value of pigment were studied.The results show that the C@ZrSiO_(4)pigment with excellent coloring performance(L^(*)=31.3,a^(*)=+1.4 and b^(*)=+1.3)can be obtained when heat treatment temperature is 1100℃,and the mass ratio of walnut shell powder/ZrSiO_(4)is 1∶3.When 5%(mass fraction)C@ZrSiO_(4)is added to transparent glaze under firing temperature of 1200℃,the black glaze exhibits excellent coloring performance with the color value of L^(*)=41.2,a^(*)=+1.2 and b^(*)=+1.7.
