Abstract:If we introduce a correction to this magnitude then the calibration curve is shifted from curve 2 to curve 4 and practically coincides with curve 3 for the ground samples (see Fig. 1).Consequently, calibration for the samples of fractions minus 0.25 mm is needed with respect to the concentration of calcium oxide in the calibrated samples, corresponding to their average grain-size composition, or, as it turned out, it is possible to use the calibration curve for the ground samples since the loss in intensity of… Show more
scite is a Brooklyn-based organization 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 and 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.
