Extract

The mass absorption coefficient is perhaps the most under-utilized parameter in x-ray diffraction analysis. Mass absorption measurements are often avoided in quantitative analysis by resorting to calibration curves of internal standards (e.g., Kung and Alexander, 1974, Sec. 7-2.1). However, Leroux et al. (1953) and Frevel and Roth (1982) directly utilized the mass absorption coefficient in multicomponent analysis, and suggested a "substrate diffraction" procedure for directly measuring the sample mass absorption coefficient. The reference intensity procedure of quantitative multicomponent analysis originally formulated by Frank Chung (1974) requires no explicit use of the mass absorption coefficient because all reference intensity ratios are determined relative to an "external" standard, generally corundum (Al2O3).
