Abstract:The thermal behavior
of ash components in two bituminous coal samples
[Upper Freeport (the “UF”) and Illinois #6 (the “IL”)]
was investigated under air and argon atmospheres in the temperature
range of 800–1200 °C using thermal gravimetric–differential
thermal analysis, X-ray diffraction transmission electron microscopy
(TEM), and TEM–energy dispersive X-ray spectrometry measurements.
The UF treated under air formed the needle-like crystals which were
assumed to be mullite-related substances formed by transfor… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
