摘要：

The fabrication and crystallization of stoichiometric and near-stoichiometric celsian, BaAl2Si2O8 (BAS), glass made via melt and sol-gel routes is reviewed. After considering celsian polymorphism and methods of stabilizing monoclinic celsian, some new experimental results are presented which show that melt glass crystallizes predominantly via surface nucleation, but sol-gel glass via volume nucleation. Possible reasons for this behavior and the kinetics of the crystallization process are examined.
