纳米SiO2在钧瓷釉料中的应用及对釉料性质的影响

在钧瓷基础釉中加入过渡金属氧化物可以使钧瓷呈现出丰富多彩的釉色,但同时也会造成严重的流釉现象.在传统钧瓷中,适当的流釉可以给瓷器带来艺术的美感,严重的流釉反而影响钧瓷的艺术效果和产品质量.通过在钧瓷釉料中添加纳米SiO2,并控制其质量比例在2wt;和4wt;,研究纳米SiO2对钧瓷釉料性质的影响.添加纳米SiO2前后的钧瓷釉料的结构和性质通过X-射线衍射仪、扫面电子显微镜和X-射线电子能谱仪进行表征分析.对比发现,纳米SiO2的添加可提高釉的化学稳定性和热稳定性,有效地改善钧瓷制品的流釉现象,并且能够提高釉层的亮度.

Application of Nano-SiO2 and Effect on the Jun Porcelain Glaze Properties

Addition of transition metal oxides in the Jun porcelain glaze could make the Jun porcelain show colorful glaze,but it also resulted in a large number of flows of glaze.In the traditional Jun porcelain,flow of glaze would bring the beauty of art.However,serious flow of glaze destroyed the artistry and quality of Jun porcelain.In order to research the effect of nano-SiO2 to the property of glaze,2wt; or 4wt; nano-SiO2 was added into the Jun porcelain glaze.The effect of adding SiO2 for the microstructure and properties of Jun porcelain glaze were studied through powder X-ray diffraction (XRD),scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS).The results show that adding SiO2 can improve the chemical stability and thermal stability of glaze.It also can decrease the flow of glaze and increase the brightness and quality of glaze.
