【摘要】：近年来,随着现代科学技术和文物鉴赏研究的发展和相互结合,越来越多的现代科技手段在古陶瓷科学研究中得到了广泛的应用,如古陶瓷的结构、元素组成、元素化学状态、热学性质、物理性能(密度、气孔率等)等的分析测试都已成为古陶瓷研究中的重要内容,其中古陶瓷的元素组成分析是古陶瓷科技研究的基础,在古陶瓷研究当中起着重要的作用,可为研究陶瓷的起源、原材料的种类、产地、烧制工艺的演化以及产品流通等提供相应的科学信息。然而,古陶瓷样品有着许多和其他样品不一样的特点,如样品的珍贵性,内部组成严重不均匀性等;同时,不同的元素组成分析技术也都有着其自身的特点和适用范围,所以如何针对古陶瓷样品的自身特点和具体的研究目标,正确的选择和应用相应的元素组成分析技术有针对性的进行不同种类古陶瓷的准确定量分析,成为古陶瓷科技研究者所关注的一个热点问题。有鉴于此,本文利用XRF、ICP-AES、湿化学方法这三种常见的元素组成分析方法对不同类型的典型古陶瓷样品进行测试分析,通过对比分析这几种方法所能测量的相应元素种类、范围和测试精度以及对样品的形态要求和样品制备的难易度,测试费用和测量用时等方面的优缺点,总结得出了严重非均匀古陶瓷、釉下彩绘瓷、高温釉和低温釉瓷所适宜的测试技术和方法;并通过实验对比深入探讨了上述各方法的最佳测试条件,针对不同种类古陶瓷样品的特殊性,初步确立了包括制样方法、测试电压、测试时间等在内的最佳实验参数条件。另外,为了利用EDXRF方法准确定量和无损分析古陶瓷釉层的元素组成,本课题在前人研究的基础上,参考古陶瓷物理化学数据库中各类古陶瓷瓷釉元素组成的特点,成功烧制成了一套利用Na_2CO_3、MgO、KNO_3等各元素的化合物化学纯为主要原料的古陶瓷釉层无损分析标准参考物质。这为古陶瓷科技研究中获取更为准确和丰富的元素组成信息提供有力的支撑。
[Abstract]:In recent years, with the development and integration of modern science and technology and cultural relic appreciation research, more and more modern scientific and technological means have been widely used in ancient ceramic science research, such as the structure of ancient ceramics, the composition of elements, the chemical state of elements. The analysis and testing of thermal properties, physical properties (density, porosity, etc.) has become an important content in the research of ancient ceramics, in which the element composition analysis of ancient ceramics is the basis of the scientific and technological research of ancient ceramics. It plays an important role in the research of ancient ceramics. It can provide scientific information for studying the origin of ceramics, the species of raw materials, the origin of raw materials, the evolution of sintering process and the circulation of products. The ancient ceramic samples have many different characteristics from other samples, such as the precious samples, the serious inhomogeneity of the internal composition, etc. At the same time, different element composition analysis techniques also have their own characteristics and applicable scope. Therefore, how to correctly select and apply the corresponding element composition analysis technology to carry out accurate quantitative analysis of different kinds of ancient ceramics according to their own characteristics and specific research objectives, It has become a hot issue that researchers of ancient ceramic science and technology pay close attention to. In view of this, three common methods of element composition analysis, XRF- ICP-AESand wet chemical method, are used to test and analyze different types of typical ancient ceramic samples, and the corresponding elements which can be measured by these methods are compared and analyzed. The scope and precision of the test, the requirements for the shape of the sample, the difficulty in the preparation of the sample, the cost of the test and the time used for the measurement, etc., have been summarized, and the serious inhomogeneous ancient ceramics, underglazed painted porcelain, and so on have been concluded. The suitable testing techniques and methods for high-temperature glaze and low-temperature glazed porcelain are discussed, and the optimum testing conditions of the above methods are discussed deeply through experimental comparison. According to the particularity of different kinds of ancient ceramic samples, the methods of sample preparation are preliminarily established. In addition, in order to accurately quantitative and nondestructive analysis of the element composition of ancient ceramic glaze layer by using EDXRF method, based on the previous studies, Referring to the physical and chemical database of ancient ceramics, the characteristics of the composition of glaze elements of various ancient ceramics, A set of standard reference materials for nondestructive analysis of glaze layer of ancient ceramics was successfully prepared by using the chemical purity of chemical compounds of various elements, such as NaSZ _ 2CO _ 3, MgO _ Kno _ 3 and so on. This is a more accurate and abundant information of element composition obtained in the scientific and technological research of ancient ceramics. Provide strong support.
