X-ray diffraction (XRD) is a non-destructive analytical technique that provides crystal structure information (crystallite size, % crystallinity, etc.), phase identification (e.g. minerals), and quantification of phases present in a sample. Modern XRD equipment is easy to use, can measure samples in minutes and provides automated, quantitative analysis. XRD can be a fast and efficient way to determine coal quality, total ash and amorphous carbon content in coal without the need for standards, monitors and calibrations.
Coal remains one of the major energy sources for the world. A fast and accurate check of ash content and the mineral matter in coal enables the early recognition of coal quality and makes fast counteractions possible. Also, some types of mineral matter can have adverse effects on the milling equipment used to grind coal, and XRD can monitor these minerals and the ratio of minerals, which affects wear of milling equipment.
