摘要

用扫描电子显微镜研究了碳化工业样品的形貌、结构和矿物组成。根据结果，碳化样品包括不同大小的颗粒，这些颗粒被一层含氧的有机物质所覆盖。在惰性气氛中将样品加热到800℃后，颗粒表面的氧含量下降，证实了分散的无定形碳酸钙也存在。炭化样品的矿物成分中含有褐煤特有的Ca和Mg元素。为样品建立的微观结构也是典型的碳化褐煤。

Analysis of Carbonized Industrial Samples by Scanning Electron Microscopy

The morphology, structure, and mineral composition of carbonized industrial samples are studied by scanning electron microscopy. According to the results, the carbonized samples include particles of different sizes, which are covered by a layer of organic mass containing oxygen. Disperse amorphous calcium carbonate is also present, as confirmed by the decrease in oxygen content at the surface of the particles after heating the sample to 800°C in an inert atmosphere. The mineral component of the carbonized sample is found to contain the elements Ca and Mg, which are typical of lignite. The microstructure established for the sample is also typical of carbonized lignite.
