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@ZrSiO4)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1 100 ℃、核桃壳粉/硅酸锆质量比为1:3时,合成的C@ZrSiO4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@ZrSiO4色料,经1 200 ℃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。

Abstract: Zirconium silicate encapsulated carbon (C@ZrSiO4) 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/ZrSiO4(theoretical synthesis, the same below) on the phase composition and chromaticity value of pigment were studied. The results show that the C@ZrSiO4 pigment with excellent coloring performance (L*=31.3, a*=+1.4 and b*=+1.3) can be obtained when heat treatment temperature is 1 100 ℃, and the mass ratio of walnut shell powder/ZrSiO4 is 1:3. When 5% (mass fraction) C@ZrSiO4 is added to transparent glaze under firing temperature of 1 200 ℃, the black glaze exhibits excellent coloring performance with the color value of L*=41.2, a*=+1.2 and b*=+1.7.

Key words: walnut shell powder, sol-precipitation method, C@ZrSiO4 pigment, phase composition, microstructure, chromatic performance
