Analysis of Melt Inclusions Defects of Flat Glass by Raman Spectra

【目的】玻璃生产过程中玻璃表面和内部经常会出现多种类型的熔融包裹体,了解包裹体的成分对分析其形成以及调整玻璃生产工艺解决质量问题至关重要,传统的分析方法在很多时候需要制片,而且需要很丰富的经验,分析过程复杂、时间长,为此提出一种新的分析方法。【方法】基于显微拉曼光谱分析玻璃表面和内部的熔融包裹体,利用特征光谱判别包裹体的物质成分。【结果】成功鉴别出玻璃原材料中的长石、白云石、硅砂以及芒硝成分的包裹体,并通过岩相分析得以证实。【结论】显微拉曼光谱技术可以作为平板玻璃生产过程中质量缺陷分析的有效手段。

Objective]There are different kinds of melt inclusions in float glass production.It is very important to know the ingredients of melt inclusions and their formations in order to realignment process parameters for solving the quality problem.The lithofacies method is the traditional analytical method,but in many cases,this method needs to cut the glass into slices,which requires rich experience,along with complex and time consuming analysis process,so a new method is induced.[Methods]With micro Raman spectroscopy spectral glass surface and internal melt inclusions are analyzed using the characteristic spectrum to distinguish ingredients of the melt inclusions.[Results]This paper successfully using Raman spectroscopy analyzes the feldspar,dolomite,silica sand as well as the composition of glauber's salt inclusions from glass raw materials,with verification by petrographic analysis.[Conclu-sion]The results show that the micro Raman spectroscopy can be used as a useful tool for quality defects analysis in flat glass production process.
