摘要
氧化石墨烯(GO)作为一种石墨烯衍生物,具有超强的机械性能和丰富的含氧官能团。利用GO改性陶瓷釉面,并研究GO含量对陶瓷釉面硬度和耐磨性的影响。研究结果表明:GO的最佳用量为0.05 wt%,哑光陶瓷釉面的硬度提升为11.4%(从642.9至716.3 Hv),磨耗从0.12 g降至0.04 g,然而亮光陶瓷釉面的性能却没有明显提升。通过XRD、TG-DSC和EDS等进一步分析,发现釉面性能提升的原因是GO能够诱导釉面析出硬度较高的SiO_(2)晶体,增强玻璃网络结构,抑制钠长石相的析出,并减少釉面的孔洞率。揭示了GO对陶瓷釉面性能影响的作用机制,这对于GO在陶瓷领域的应用具有重要的参考价值。
Graphene oxide(GO),as a derivative of graphene,possesses exceptionally strong mechanical properties and abundant oxygen-containing functional groups.In this work,GO was used to modify ceramic glazes,and the effect of GO content on the hardness and wear resistance of ceramic glazes was investigated.The research results indicate that the optimal amount of GO is 0.05 wt%,which increases the matte ceramic glazes hardness to 11.4%(from 642.9 Hv to 716.3 Hv)and reduces wear from 0.12 g to 0.04 g.However,there is no significant improvement in the performance of the glossy ceramic glaze.Further analysis through XRD,TG-DSC,and EDS reveals that the glazes performance enhancement is due to the ability of GO to induce the precipitation of SiO_(2) crystals with higher hardness,strengthen the glass network structure,inhibit the crystallization of the sodium feldspar phase,and reduce the porosity of the glaze.This paper revealed the mechanism by which GO affects the properties of ceramic glazes,and this is of great significance for the application of GO in ceramics.
