摘要
提高陶瓷釉面耐磨性是改善日用陶瓷制品耐久性和使用性能的一种重要途径。以提高釉面的耐磨性为目标,研究釉料主要化学成分对釉面耐磨性能、色度和光泽度的影响。研究发现:釉料Si/Al=3.5~4.8时,提高釉料中Al_(2)O_(3)含量,能有效提高陶瓷釉面硬度,与原始釉料相比最高可提升80.3%。釉料Si/Al=4.8~5.0时,提高釉料中SiO_(2)含量,则最高可提高釉面硬度48.4%。增加釉中的CaO与MgO含量,有助于提高釉面的硬度,但随其含量增多,釉面色度和光泽度降低。在低Si/Al条件下,适当增加釉料中MgO和CaO的含量可增加釉面的硬度和光泽度。
Enhancing the wear resistance of ceramic glaze is an important way to improve the durability and service performance of domestic ceramic products.In order to improve the abrasion resistance of glaze,effects of the main chemical compositions of glaze on the abrasion resistance,the chromaticity and glossiness of glaze were studied.It is shown that the Si/Al ratio in the glaze has great influence on the hardness of the glaze surface,with a slight change in the chromaticity and glossiness.For the Si/Al ratio being 3.5~4.8,increasing the Al_(2)O_(3)content in the glaze could effectively improve the ceramic glaze hardness,with a maximum growth value of 80.3%when compared with that of the original glaze.When the ratio of Si/Al ratio is 4.8~5.0,increasing the content of SiO_(2)in glaze could effectively improve the hardness a maximum growth value of 48.4%.Excessive or low Si/Al ratio would affect the melting temperature of glaze and lead to the decline of optical properties of glaze.Increasing the content of CaO and MgO in the glaze is helpful to improve the glaze hardness.However,with the increase of CaO and MgO contents,a large number of crystals are precipitated into the glaze,easily giving rise to a decrees in the color and glossiness of glaze.Under low Si/Al ratio,the moderate increase of the contents of MgO and CaO could increase the hardness and glossiness of the glaze.
