This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request of the authors due to serious errors in the article discovered after publication. In particular, the evaluated ΔSº and ΔHº values reported in Table 1 contain large errors, leading to errors in derived equilibrium constants, because equilibrium states are not completely achieved during scanning TG-DTA. These errors may explain the large discrepancies in ΔSº and ΔHº observed between these measurements and those reported by Shirsat et al.  and calculated by Yokokawa et al.  In order to obtain sufficient accuracy, equilibrium thermogravimetry is necessary.
