摘要

在1280℃下，通过调整na2o / k2o和r2o / al2o3的质量分数，成功制备了具有良好表观质量和水润湿性的透明陶瓷釉料。研究了na2o / k2o和r2o / al2o3配比对陶瓷釉的表面能和光泽度的影响。结果表明:na2o / k2o和r2o / al2o3的质量分数比对釉料的高温粘度、熔融温度、釉网结构密度和釉上断裂键数有明显影响;当na2o / k2o = 0.8 ~ 1.6, r2o / al2o3 = 0.8 ~ 1.2时，釉的光泽度为88.3 ~ 108.3，提高了0.11 ~ 12%，表面能为70.17 ~ 78.5 mJ·m -2，提高了5.62 ~ 29.55%，明显高于碱性釉。釉的表面能越大，极性成分越大，水在釉上的润湿性越好，有利于提高陶瓷制品的防污和易清洗性。

EFFECT OF ALKALI METAL OXIDES ON THE SURFACE ENERGY OF CERAMIC GLAZE

A transparent ceramic glaze with good apparent quality and water wettability was successfully prepared by adjusting the mass fraction ratio of Na 2 O/K 2 O and R 2 O/Al 2 O 3 at 1280 ℃. The effects of the Na 2 O/K 2 O and R 2 O/Al 2 O 3 ratios on the surface energy and glossiness of the ceramic glaze were studied in the present work. The results show that the mass fraction ratio of Na 2 O/K 2 O and R 2 O/Al 2 O 3 showed an obvious effect on the high temperature viscosity and melting temperature of the glaze, the density of the glaze network structure and the number of broken bonds on the glaze. When Na 2 O/K 2 O = 0.8 – 1.6, R 2 O/Al 2 O 3 = 0.8 – 1.2, the glaze showed a glossiness of 88.3 – 108.3 with a 0.11 – 12 % increase, and the surface energy of 70.17 – 78.5 mJ·m -2 with a 5.62 – 29.55 % increase, being obviously higher than those of the basic glaze. The greater the surface energy of the glaze was, the greater the polarity component was, and the better the wettability of the water on the glaze was, which would be conducive to improving the antifouling and easy cleaning of ceramic products.
