Abstract
The thermal transformation of sodium bicarbonate to anhydrous sodium carbonate was studied in an open system between 82°C and 95°C by an x-ray powder diffraction method, The kinetic behavior of this transformation for finely ground material can be ascribed to the “diminishing sphere” model (l/3 order). In the transformation process an intermediate state lacking crystallinity was observed. This state is attributed to the formation of numerous surface nuclei of anhydrous sodium carbonate.Keywords
