摘要: A value of 20.1 +/- 4 kcal/mole for the activation energy (E) hexacelsian to celsian phase transformation in BaAl2Si2O8 was reported an earlier work. In present work, experimental data were reanalyzed and a much higher E obtained. This revised is consistent with mechanism layered structure into three-dimensional feldspar which would necessitate breaking Si-O and/or Al-O bonds.
