Abstract
X-ray diffraction, infrared spectroscopy, and thermal methods of analysis were used to resolve conflicting statements in the literature on the thermal decomposition of dawsonite [naal(oh)2co3]. By 350 deg c the dawsonite structure collapses and water equivalent to the hydroxyl group and a large portion of the carbonate co2 are lost. This decomposition product then gradually loses the remainder of the co2 and remains amorphous until crystalline naalo2 is formed at approximately 670 deg c.
