Current approach to identification of corrosion mineral phases on heat metal surfaces at coal combustion
Анотація
One of the most effective methods for identifying the mineral composition of various substances is the X-ray diffraction method [1]. The universal software package Match! (Crystal Impact) is used to analyze X-ray data. A difficult task is to determine the quantitative composition of the identified compounds, primarily those that have a small content in the investigated substance. Recording of X-Ray data of coal ash with a high content of salts ([Na2O] in the ash ≥ 2 %, i.e. salty coals (SC), which determines its high corrosion activity, and scales exfoliated from the surface of steel plates was made by the DRON 4M device.
