摘　　要：由于陶瓷釉层的透明度难以量化测量,对利用色差测量陶瓷釉层透明度的方法进行研究。通过在透明釉中添加莫来石、硅酸锆和二氧化锡等晶体,在坯体上施釉、干燥并烧成,制备了不同透明度的陶瓷釉样品。分别研究了晶体种类和添加量、釉层厚度、坯体底色和釉面状况对色差的影响。结果表明,色差与晶体添加量存在较好的线性关系,同时如果晶体折射率越大,色差也越大,原因是晶体对光的散射;釉层厚度增大,色差快速增加,原因是厚度增加引起了大气泡的增多。坯体底色对色差几乎没有影响,釉面被腐蚀后表面粗糙对色差有一定的影响。该方法简单,适应性好,可以作为陶瓷釉层透明度的评价方法。Due to the difficulty in quantitatively measuring the transparency of the ceramic glaze layer,a color difference method to assess the transparency of the ceramic glaze layer was studied in this study.By adding crystals such as mullite,zirconium silicate,and tin dioxide to transparent glazes,glazing,drying,and firing on green body,ceramic glaze samples with different degrees of transparency were prepared.The effects of crystal type and addition amount,glaze thickness,base color of the green body and glaze surface condition on color difference were investigated separately.The results show that there is a good linear relationship between the color difference and the crystal addition amount.At the same time,the greater the crystal refractive index,the greater the color difference due to the scattering of light by the crystals.Additionally,with the glaze thickness increased,the color difference increased rapidly,which is attributed to the increase in large air bubbles caused by the increased thickness.The base color of the green body had minimal impact on the color difference,while surface roughness after glaze erosion had a certain effect on the color difference.The method is simple,adaptable and can be used to evaluate the transparency of ceramic glazes.
