我们证明了拉曼光谱作为一种技术，用于鉴定古代玻璃和搪瓷涂层的陶瓷的效用。对于任何硅酸盐玻璃，网络改性剂的加入破坏了Si-O键并改变了聚合度，因此改变了Si-O弯曲和拉伸模式的相对强度。我们的经验表明，这些信封的比例是很好地相关的玻璃结构和所使用的烧制技术。光谱Q”组件分配给孤立和连接的SiO 4振动单元允许更精确的分析。对代表不同亚洲、伊斯兰和欧洲生产技术的选定瓷器、彩陶、陶器和玻璃进行了研究。现代瓷釉被用作成分参考。(C)2003 Elsevier B. V.保留所有权利。
We demonstrate the utility of Raman spectroscopy as a technique for the identification of ancient glasses and enamel coatings of ceramics. As for any silicate glasses, the addition of network modifiers breaks the Si-O linkages and modifies the degree of polymerization and hence the relative intensity of the Si-O bending and stretching modes. We demonstrate empirically that the ratio of these envelopes is well correlated to the glass structure and to the firing technology used. Spectral Q" components assigned to isolated and connected SiO4 vibrational units allow more precise analysis. Selected porcelains, faiences, potteries and glasses representative of the different Asian, Islamic and European production technologies were studied. Modern porcelain enamels are used as compositional references. (C) 2003 Elsevier B.V. All rights reserved.
