Title: Infrared Absorption Spectra of Minerals and Other Inorganic Compounds
Abstract: A method is described for utilizing the infrared spectrophotometer in the analyses of minerals and other inorganic compounds. Mineral samples are ground to a powder having an average particle diameter smaller than 5 microns. The powder is deposited as a film on a conventional rock salt window. The spectra of 64 minerals, rocks, and inorganic chemicals are shown for the wavelength region from 2 to 16 microns. Spectral positions of the principal absorption bands of these compounds are tabulated. The technique is used in the study of fine-grained rocks. Analytical chemists in other fields such as catalysis, soils, and ceramics may find the same methods applicable to their problems.
