Abstract
The fabrication and crystallization of stoichiometric and near-stoichi ometric celsian, BaAl2Si2O8 (BAS), glass made via melt and sol-gel rou tes is reviewed. After considering celsian polymorphism and methods of stabilizing monoclinic celsian, some new experimental results are pre sented which show that melt glass crystallizes predominantly via surfa ce nucleation, but sol-gel glass via volume nucleation. Possible reaso ns for this behavior and the kinetics of the crystallization process a re examined.
