• Description:
  To determine the nahcolite and dawsonite content in oil shales, the Bureau of Mines compared x-ray diffraction, infrared spectroscopy, thermal methods, and a previously published method by smith and young based on the selective solubility of sodium compounds. The smith and young method and a new method based on the weight of carbon dioxide produced by thermal decomposition are recommended for determining nahcolite. X-ray diffraction and the smith and young method are recommended for determining dawsonite. X-ray diffraction, infrared spectroscopy, and differential thermal analysis were useful for identifying other minerals in the samples. [Description provided by NIOSH]
