X-Ray Analysis of the Argonne Premium Coals .1. Use of Absorption Diffraction Methods
Chemistry and Biochemistry
The eight coals that constitute the Argonne Premium Coal Sample Program have been measured by a modified X-ray diffraction technique from which the mass absorption coefficient for each coal was measured for copper Ka X-rays. With the use of its mass absorption coefficient, the diffracted intensity measured for each coal was converted to its absorption-corrected intensity, I'(2 ). From peak areas in (2 ) the abundances of -quartz, calcite, and pyrite were measured. The principal silicate(s) in each coal was(were) identified, and their abundances were crudely estimated from the absorption-corrected diffractograms.
