高温无光釉的研制

摘要

在控制Al2 O3/SiO2摩尔比为1∶（3～4）时，通过改变钾长石和高岭土的含量，考察钾长石和高岭土含量以及外加锆黄和紫金土对釉面的影响。实验结果表明：当配方组成为（质量％）：钾长石48．5，高岭土29．9，石灰石22．6，石英13．5，最佳工艺参数为：烧成温度1280℃，保温时间20 min时，得到了光泽度为8．6％，白度为74．5％的高温无光釉。%Controlling Al2 O3/SiO2 molar ratio of 1∶ (3~4) ,effects of the potash feldspar and kaolin ,and the additives such as zirconium yellow and purple soil on high -temperature matt glaze were studied ,The results showed that when the glaze composition such as potassium feldspar 48 .5 ,kaolin 29 .9 ,limestone22 .6 ,dolomite limestone 14 .5 ,quartz 13 .5 ,was fired at 1 280 ℃ for 20 minutes ,the gloss and whiteness of the high -temperature mat glaze were 8 .6% and 74 .5% ,re-spectively .
