"The decomposition rate of strontium carbonate (SrC0₃) was measured using a TGA apparatus. It was found to deviate slightly from zero order classical reaction. The rate of formation of strontium zirconate (SrZr0₃) from zirconium oxide (ZrO₂) and strontium oxide (SrO) in the form of the decomposition product of SrCO₃ was measured using quantitative x-ray diffraction for mineralogical analysis. It was found to most nearly follow the Zhuravlev-Lesokhin-Tempel' man rate equation. The rate of decomposition of strontium carbonate was found to be more rapid than the rate of formation of strontium zirconate such that for the most part strontium oxide is reacting with the zirconium oxide. The activation energies for the decomposition of strontium carbonate and the formation of strontium zirconate from zirconium oxide and the decomposition product of strontium carbonate were calculated to be 50.6 ł 2.6 kilocalories per mole and 81.3 ł 9. 7 kilocalories per mole, respectively. The Hedvall effect was observed in the rate of formation of strontium zirconate at the transformation temperature of zirconium oxide"--Abstract, page ii.
